Making interpretations: On the graph,
scientists can derive additional information from the numerical data
, such as how fast CO

concentration is rising. This rate can be determined by calculating the slope of the long-term trend in the numerical data, and seeing this rate on a graph makes it easily apparent.

What property of oil makes it float on water quizlet?
The property of oil that allows it to float in water is
it’s DENSITY
. Oil is less dense than water and dose not mix with water, allowing the oil to float on water.
Why would heating gas in a balloon make it rise?
Hot air rises. Heated air molecules “spread out” or expand and bounce around, and the space becomes less dense than the surrounding space.
Increasing the air temperature inside the balloon envelope
makes it less dense than the air, thus making it “lighter than air”.
Is a body temperature of 39.4 CA normal temperature or does it indicate a fever?
A low-grade fever for adults and children is when your body temperature is elevated slightly above normal. This is generally between 98.8°F (37.1°C) and 100.3°F (38°C). People with high-grade fevers should seek medical advice. For adults, this is an oral temperature of
103°F
(39.4°C).
What properties of oil makes it float on water?
The buoyant force
What is relation between density and specific gravity?
Density is defined as mass per unit volume. It has the SI unit kg m
– 3
or kg/m
3
and is an absolute quantity. Specific gravity is
the ratio of a material’s density with that of water at 4 °C
(where it is most dense and is taken to have the value 999.974 kg m
– 3
). It is therefore a relative quantity with no units.
What causes the density of a balloon to decrease?
The
stronger outside air pressure
compresses the balloon. As the balloon volume decreases, pressure inside the balloon increases. It eventually is able to balance the outside air pressure. … If you warm a parcel of air the volume will increase and the density will decrease.
What causes a balloon to rise?
Science tell us that
hot air rises
, and as the air is heated inside the balloon it causes it to rise upwards (because it is lighter than the cooler air on the outside). When the pilot needs to bring the balloon down again, he simply reduces the temperature of the air inside the balloon causing it to slowly descend.
How does Charles Law relate to hot air balloons?
This relationship
between the temperature and volume of a gas
, which became known as Charles’ law, provides an explanation of how hot-air balloons work. … If a gas expands when heated, then a given weight of hot air occupies a larger volume than the same weight of cold air. Hot air is therefore less dense than cold air.
Which temperature is normal for Covid 19?
You probably always heard that the average human body temperature is 98.6 F. But the reality is that a “normal” body temperature can fall within a wide range, from
97 F to 99 F.
It’s usually lower in the morning and goes up during the day.
How do I check my temperature with an infrared thermometer?
An infrared thermometer can be used
on both the forehead and wrist
. Just make sure that the body surface is dry and clean to get correct readings. You also need to ensure that the thermometer is used from the ideal distance so that it can sense the body temperature correctly.
Does oil float on water or sink in it answer?
Because oil is less dense than water,
it will always float on top of water
, creating a surface layer of oil. You might have seen this on streets after a heavy rain—some water puddles will have a coating of oil floating on them.
Is oil more buoyant than water?
Oil is
less dense than water
, so 1 cubic cm of oil weighs less than 1 cubic cm of water. Therefore, the upward buoyancy force on the oil, which is equal to the weight of water displaced, is greater than the downward force of gravity on the oil, also known as the weight of the oil.
Is oil denser than water?
Since the oil is lighter, it is
less dense than water
and floats on water.
