Gray Granite
– With a specific heat of almost three tenths that of water, gray granite has the highest specific heat of the materials by a significant margin. This means it has a large heat capacity, and requires a relatively large amount for heat energy to raise its temperature.
What material has the highest specific heat?
Water
has the highest specific heat capacity of any liquid. Specific heat is defined as the amount of heat one gram of a substance must absorb or lose to change its temperature by one degree Celsius.
Which of the following has highest specific heat?
The Correct Answer is Option 1, i.e.
Water
. Water has the highest specific heat capacity any liquid can produce. Specific heat is defined as the amount of heat one gram of material has to absorb or lose to change one degree Celsius in temperature. That amount is one calorie per vapour or 4.184 Joules for water.
What is high specific heat?
A high specific heat capacity means
it can hold a large amount of thermal energy in for a low mass or temperature change
. It is also good at keeping in thermal energy, for example: Object: Mass = 3kg.
Which type of materials have high specific heat What does it mean?
Specific heat is a measure of how much energy it takes to raise the temperature of a substance. … Specific heat is a property that is specific to a given type of matter, and substances vary in their specific heat. Metals tend to have low specific heat.
Water
has very high specific heat.
Does aluminum have a high specific heat?
The aluminum’s temperature changed less than the copper’s did under the same conditions. Thus, the aluminum must require more energy to change its temperature. Therefore,
aluminum has the higher specific heat
.
Which has the higher specific heat capacity water or sand?
Water has a very high specific heat
. That means it needs to absorb a lot of energy before its temperature changes. Sand and asphalt, on the other hand, have lower specific heats. This means that their temperatures change more quickly.
Why do some materials have a higher specific heat?
The amount of energy required to raise the temperature of a particular amount of substance is determined by the molecular level structure of the material. … Usually, more complex substances have a higher molar heat capacity, since
larger molecules have more possible ways to vibrate, bend and rotate
.
Does higher specific heat mean higher temperature?
Explanation: Specific heat is Jg−oK . So,
a high value means that it takes MORE energy to raise (or lower) its temperature
. … Adding heat to a “low specific heat” compound will increase its temperature much more quickly than adding heat to a high specific heat compound.
Does brick or iron have a higher specific heat?

Does air have a high specific heat?
| Substance Heat Capacity (Jkg – 1 K – 1 ) | Air 700 |

Which material has the higher specific heat soil or water?
Because
water
has a much higher heat capacity, or specific heat, than do sands, soils or other materials, for a given amount of solar irradiation (insolation), water temperature will increase less than land temperature.
What metal has a specific heat of?

Which material has the lowest specific heat capacity?
Mercury
has a low specific heat capacity . Therefore it does not take much heat from the body whose temperature is to be measured. Otherwise it will lower the temperature of the body.
Why is specific heat higher for polymers?
Heat Capacity of Polymers
It is usually measured in Joules per Kelvin and kilogram (or mole). … The
heat capacity increases with increasing temperature
, therefore, a liquid or rubbery polymer can hold more energy than a solid polymer. All materials show this increase in heat capacity with temperature.
What does it mean to say that a material has a high or low specific heat capacity?
A substance with a high specific heat
capacity can absorb a large quantity of heat before it will raise in temperature
(water has a high specific heat). A substance with a low specific heat requires relatively little heat to raise its temperature (copper has a low specific heat).
What material can hold the most energy water iron or brick?
Sample Answer
The
water
has more energy than either the iron or brick because it is in the liquid state at room temperature. Particles in liquids have more kinetic energy than particles in solids.
What is the specific heat of iron?
| Substance specific heat capacity C p , s (J/g °C) molar heat capacity C p , m (J/mol °C) | iron 0.450 25.09 | lead 0.129 26.4 | lithium 3.58 24.8 | mercury 0.14 27.98 |

What is high heat of vaporization?
One unique property of water is its high heat of vaporization. Heat of vaporization refers to the
energy required to convert one gram of liquid into a gas at boiling point
. … The dominant intramolecular force that leads to this high heat of vaporization in water is hydrogen bonding.
Does air or water have higher specific heat?
Water’s specific heat capacity is 4200 Jkg
– 1
K
– 1
and Air’s is 993 Jkg
– 1
K
– 1
therefore
water
has 4.23 times more specific heat capacity. Water has a density of 1000/m
3
and air has a density of 1.275/m
3
therefore water would be 784.31 x denser than air.
What is the specific heat of rock?

Is specific heat intensive or extensive?
The specific heat capacity
is intensive
, and does not depend on the quantity, but the heat capacity is extensive, so two grams of liquid water have twice the heat capacitance of 1 gram, but the specific heat capacity, the heat capacity per gram, is the same, 4.184 (J/g
.
K).
Which has a higher specific heat water or sand Class 11?
This is because
water
has a higher specific heat capacity than sand – meaning that it takes a lot of heat, or energy, to raise the temperature of water one degree, whereas it takes comparatively little energy to change the temperature of sand by 1o.
Why do metals have a low specific heat?
Metal atoms in pure metal are very close together and are able to transfer heat easily via conduction from one atom
exciting the other atoms next to it. … So the amount of energy it takes to heat a metal is relatively small to that of water for example.
