Question

For college physics discussion post. Please type out the answer in paragraph form and do not submit a photo as it is hard for me to read.

Describe the difference between temperature and heat, and give examples.

In your own words, explain the difference heat and specific heat capacity.

In your own words, explain types of heat transfer and give examples.

In your own words, explain types of phase change and give examples.

Answer 1

1)Heat:

a form of internal energy.

SI unit is joule.

The amount of heat energy contained in a body depends on its mass, temperature and material.

Measured using the principle of calorimetry .

Two bodies that have the same amount of heat energy can differ in their temperature.

Temperature:

Determine which direction the heat energy will flow in.

Its SI unit is kelvin.

The temperature of a body depends on the average kinetic energy of its molecules.

measured by thermometer.

Two bodies at the same temperature can contain different amounts of heat energy.

2)heat is the amount of internal energy storwd in a body wheareas specific heatcapacity of a body is the amount of heat required to raise the temperature of that body by unit temperature.

3)Types of heat transfer-

a) Conduction- eg friction.

b)convection- eg heat dissipation in bottle.

c)radiation-eg space

4)phase change-

a)melting-conversion of solid to liquid.eg.ice to water

b)boiling-conversion of liquid to gas.eg.boiling of water

c)sublimation-conversion of solid to gas.eg napthalene balls
