Hence water is suitable to be used as a coolant in motor cars and air-conditioners. On the other hand, the hot drink cooled by the 0-?

Air around the lumps is heated. The different expansions of strips make the bimetallic strip bend one way. After turning vertical, the weight of the piston is not balanced. This shows that more energy is needed to vaporize the water. Heat always flows from a body with higher temperature to a body with lower temperature.

For liquids and gases, the particles are held by weaker forces and can move from one place to another. C condenses to water at ? The slope for stage X is greater than that for stage Y, i. C 7 Let c be the specific heat capacity of the metal block. If it is windy, the evaporation rate, and therefore the rate at which our bodies lose energy, will be higher.

The different expansions of strips make the bimetallic strip bend one way. The metals expand at different rates as they are heated. If it were dull black, the astronaut would radiate energy quickly and feel very cold.

Paint the walls of the room with light colours. The spacesuit is white in colour to reduce energy loss through radiation.

The opening lets the warm air flow out to prevent overheating. This shows that more energy is needed to vaporize the water. If the heating element of an electric kettle is fixed at the top, water at the ottom cannot be heated through convection.

We would feel much cooler. C to that at 20? Energy lost by the 80? Since dull black surfaces are good absorbers of radiation, the blackened foil will absorb the largest amount of radiation from the sun.3B Wave Motion II Chapter 5 Nature of Waves.
