Because it is in contact with something colder. When a warmer body is in contact with a cold body, the warmer one will give off heat to the cold one. This cools the warmer one and warms the cooler one.
The volume of water in an open system decreases when you heat it because you make it easier for the water to evaporate, causing the volume to decrease.
In a closed system, water will expand when heated, as it cannot evaporate.
NOTE: Between 0 and 4 °C, water contracts as it heats. At 4 °C it reaches its maximum density and further heating causes it to expand.
because water atoms become power full due to heat energy and repulsive force increase so distance between atoms increase so at result volume of water increase
The heat from the boiled water will escape into the surrounding air, so cooling the water.
The volume increase.
On heating water from O0c to 4oc the volume of water decreases while that of wax increases.
When a substance is heated it's volume will increase.
Its volume decreases from 0° to 4°, and then increases from 4° to 10°.
if its there long enough and gets hot enough and you drop it in water, it goes kaboom and shoots out its contents-trust me
The volume increase.
Because of the Brownian motion inside the water.
On heating water from O0c to 4oc the volume of water decreases while that of wax increases.
they are moving faster
Expansion.
When a substance is heated it's volume will increase.
because when the water is heated , the gas came out . So , the volume of the air in the tube increased .
it increase as a result of pressure generated from the heat
the volume of a solid this that humans do to warm up
The volume would increase as the pressure of the expanding air increases.
When steel (or indeed anything) is heated its mass does not change. Volume is altered by cooling and heating. In this case the volume of the steel would increase.
The liquid will expand, it's volume will increase. If it becomes heated enough, it will evaporate (turn into a gas). The more heated it becomes, the more its volume must increase to keep the same pressure.
