the chocolate bunny was melting because of radiation, conduction and convection
what is heat?
heat is the ____________ that is transferred between objects of different temperatures. objects of a __________ temperature will transfer energy to objects of a ____________ temperature.
heat is measured in two ways: ____________ or ____________.
how are heat and thermal energy related?
when heat is ____________ or __________ from a substance, it’s temperature and thermal energy will be ____________.
heat is not a ____________ of a substance like thermal energy and __________ are. heat is a form of ____________.
when two objects that have ____________ temperatures come into contact, energy will always be __________. the object with a __________ temperature will transfer energy in the form of heat, to the object of a __________ temperature until they both reach the ____________ temperature.
how can energy transfer as heat?
there are ______________ ways to transfer energy as heat.

1. conduction is when ____________ energy is transferred from one object to another through ____________ contact.

Explanation:

To solve the fill - in - the - blanks related to thermal energy and heat, we use the basic concepts of thermodynamics:

What is Heat?

• Heat is the thermal energy that is transferred between objects of different temperatures. Objects of a higher temperature will transfer energy to objects of a lower temperature.
• Heat is measured in two ways: Joules or calories.

How are Heat and Thermal Energy Related?

• When heat is added or removed from a substance, its temperature and thermal energy will be changed.
• Heat is not a property of a substance like thermal energy and temperature are. Heat is a form of energy transfer.
• When two objects that have different temperatures come into contact, energy will always be transferred. The object with a higher temperature will transfer energy in the form of heat, to the object of a lower temperature until they both reach the same temperature.

How Can Energy Transfer as Heat?

• There are three ways to transfer energy as heat.
• Conduction is when thermal energy is transferred from one object to another through direct contact.
