These questions are multiple choice to fill in the blank:
When cooking something in an oven:
1. a glass pan is an example of heat _________.
a)radiation
b)conduction
c)convection
2. a metal pan is an example of heat _________.
a)radiation
b)conduction
c)convection

To answer these questions, we need to understand the different methods of heat transfer. Heat can be transferred through radiation, conduction, and convection.
1. When cooking something in an oven using a glass pan, heat is transferred through conduction. Conduction is the transfer of heat through direct contact between particles or objects. In this case, the glass pan directly touches the food, allowing heat to transfer from the oven to the pan and then to the food.
2. When cooking something in an oven using a metal pan, heat is transferred through conduction as well. Similar to the glass pan, the metal pan comes into direct contact with the food and transfers heat from the oven to the pan and then to the food.
Therefore, the answers to the multiple-choice questions are:
1. a) radiation
2. b) conduction
