science thermal heat

heat

energy moving from a warmer object to a cooler object

temperature

a measure of the average kinetic energy of the particles of matter

thermal energy

total energy of the particles in a substance

a cold drink sits on a warm table. which way does heat move

table to drink

two cups are both 40 celsius. one has more water. which is true

they have the same temperature

when metal warms its particles move:

faster

equal masses of iron and water receive the same energy. which warms more?

iron

which has the smallest temperature change when it receives energy

water

put copper, nickel, and water in order from. BIGGEST to SMALLEST temperature change.

copper, nickel, water

a sample warms from 16 celsius to 29 celsius. calculate its temperature change.

29-16=13 celsius

to slow heat transfer

metal and plastic are the same temperature. metal feels colder because;

transfers energy from your hand faster

conduction

heat transfer by direct contact

convection

heat transfer by movement of liquids and gases

radiation

heat transfer by waves; no touching needed
