This model best represents which phase of matter? Solid, liquid, gas, plasma

gas

To change matter from a solid to a liquid, what needs to happen? --liquid needs to be added --heat needs to be removed --heat needs to be added --energy needs to be removed

--heat needs to be added

In order for conduction of heat to occur, what needs to be present? --ONLY two areas of different temperature --contact between MORE THAN two areas of different temperature --ONLY two areas of different temperature that are touching --AT LEAST two areas of different temperature are touching

This model shows which phase of matter? solid, liquid, gas, plasma

--liquid

When a hot washer is placed in room temperature (RT) water, --hot washer molecules take energy from RT water --hot washer molecules give energy to RT water molecules --the water and washers stay the same temperature --the washer will heat up

--hot washer molecules give energy to RT water molecules

Thermal energy is --heat in matter --kinetic energy in matter --kinetic energy and energy of attraction in matter --energy of attraction in matter

--kinetic energy and energy of attraction in matter

Temperature is the --measure of average kinetic energy in molecules in a system --measure of how heat is transferred between systems --conduction of heat between systems --measure of seasons

--measure of average kinetic energy in molecules in a system

In ice water, energy water gains is transferred to ice & the temperature stays the same. True or False?

True

As ice water is heated the temp will increase when there are two phases of matter present. True or False?

False

The image represents which phase of matter? solid, liquid, gas, plasma

solid

As ice water is heated, the temp will increase when there is one phase of matter present. True or False?

true

As water is heated, the temp increases because --molecules gain kinetic energy and move faster --the molecules energy of attraction increases --the molecules slow down and get closer to each other --the molecules get bigger and hold more heat

--molecules gain kinetic energy and move faster

As heat is added to a solid, the molecules gain --energy which allows condensation to occur --attraction for each other and decrease in volume --kinetic energy so that freezing can occur --enough energy to change position & change to liquid

As heat is removed from matter, evaporation & melting occur as molecular motion increases. True or False?

False

Heat energy always wants to move from areas that are colder to areas that are warmer. True or False?

False
