Water has a high specific heat. It takes the addition of a lot of energy to heat up and the loss of a lot of energy to cool down.
What is an example of high heat capacity?
If a metal chair sits in the bright sun on a hot day, it may become quite hot to the touch.
An equal mass of water in the same sun will not
become nearly as hot. We would say that water has a high heat capacity (the amount of heat required to raise the temperature of an object by 1°C.)
What is a real life example of specific heat?
Uses of specific heat in daily life
Substances having a small specific heat capacity, are very useful as material in cooking instruments such as
frying pans
, pots, kettles and so on, because, when small amount of heat is applied it will heat quickly. Water used in fire fighting.
What objects have a high specific heat?
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.
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.

What is specific heat of air?
At 300 K (27oC) , the specific heat of air is
1.005 kJ/kg⋅K
.
Why is specific heat of water so high?
Water has a higher specific heat capacity
because of the strength of the hydrogen bonds
. It requires a significant of energy to separate these bonds.
Which metal has the highest heat capacity?
| Substance Specific Heat (J/g°C) | Iron (s) 0.449 | Lead (s) 0.129 |
|---|
What heat capacity tells us?
Heat capacity is
the ratio of the amount of heat energy transferred to an object to the resulting increase in its temperature
. … Specific heat capacity is a measure of the amount of heat necessary to raise the temperature of one gram of a pure substance by one degree K.
What has a higher specific heat than water?
252, it is stated:
Hitherto water
has been regarded as possessing a greater specific heat than any other body excepting hydrogen. E. Lecker has shown to the Vienna Academy that mixtures of methylic alcohol and water have a specific heat higher than that of water, and accordingly take the second place, &c.
How does high specific heat support life?
Finally, the high specific heat of water makes it resistant to temperature change, allowing
life forms to maintain relatively constant internal temperatures
. The high specific heat and surface tension of water contribute to its high boiling point, helping to keep it in liquid form for most biological processes.
Does ice have a high specific heat capacity?
Explanation: The specific heat capacity, or the amount of heat needed to raise the temperature of a specific substance in a specific form one degree Celsius, for water is 4.187 kJ/kgK, for ice
2.108 kJ/kgK
, and for water vapor (steam) 1.996 kJ/kgK.
How do you find specific heat?
Specific heat is the amount of heat required to raise one gram of any substance one degree Celsius or Kelvin. The formula for specific heat is the
amount of heat absorbed or released = mass x specific heat x change in temperature
.
Does high specific heat mean longer to cool?
Explanation: Specific heat is Jg−oK . So,
a high value means that it takes MORE energy to raise (or lower) its temperature
. A low value means that it does not take very much energy to heat or cool it.
What is Q in Q MC ∆ T?
Q = mc∆T. Q = heat energy (Joules, J) m = mass of a substance (kg) c = specific heat (units J/kg∙K) ∆ is a symbol meaning “the change in”
