Thermal energy

All objects are made of small particles constantly in motion

• true

• false

Solids only are made of small particles

arranged in specific way in different objects ( P.E. ) .

• true

• false

Is the total K.E. and P.E. of   all particles in an object .

• thermal energy

• chemical energy

• mechanical energy

When you heat most of substances the kinetic energy of particles increases

• true

• false

When you freeze most of substances

contract and take up less spaces .

• true

• false

Heat transfers from the warmer to the cooler until the two objects have the same temperature

• true

• False

-When the ice pop is held in the sunlight , the particles lose K.E. due to increasing temperature.

• true

• false

-Temperature can be measured by ....................

• hygrometer

• thermometer.

-Is a measure of the average K.E. of the particles in a substance .

• temperature

• thermal energy

• chemical energy

If the temperature of an object is 0C so its temperature will be ...............kelvin

• 273

• -273
