Your family is toasting marshmallows over a campfire. This is an example of which type of heat transfer?

Heat is the movement of thermal energy from a warmer substance to a cooler substance. Which of the following would be the best hypothesis to investigate heat transfer?
If heat is transferred, one material will decrease in temperature, and another material will increase in temperature.
Temperature measures the average kinetic energy of the particles in a material, so you need to record the temperature of all materials you study.
Heat can be transferred by the movements of currents in a fluid, such as water boiling in a pot.
If heat is transferred, good conductors such as metals or floor tiles must be involved, and they will show a change of temperature.
The diagram compares the particles in three different states of matter. What process causes particles in the first state to change to the middle state?
condensation
evaporation
freezing
melting
Which of the following is an example of an endothermic change?
an ice cube melts
a car burns fuel
a lantern provides light
a radiator heats a home
