You buy a lava lamp from the store. As the lamp heats up, blobs of liquid rise to the top then sink back down to the bottom. This process continues because of _____________.

You are doing your homework at a desk that is underneath a lamp. You start to feel hotter because of _____________ from the lamp.

Your best friend has a bunk bed. You move from the bottom bunk to the top bunk and notice that the air is warmer. The warm air rises because of _____________.

You are in science class and want to see if the hot plates were used recently. You place your hand over the hot plate. Without touching the hot plate, your hand feels warmer. Heat is transferred to your hand by ________________.

You are roasting marshmallows at a campfire. The metal skewer (stick) that you’re cooking your marshmallow on burns your hand because of _________________.

Explanation:

You are stirring a bowl of hot soup with a metal spoon. The spoon starts to feel warmer because of Conduction.

You buy a lava lamp from the store. As the lamp heats up, blobs of liquid rise to the top then sink back down to the bottom. This process continues because of Convection.

You are doing your homework at a desk that is underneath a lamp. You start to feel hotter because of Radiation from the lamp.

Your best friend has a bunk bed. You move from the bottom bunk to the top bunk and notice that the air is warmer. The warm air rises because of Convection.

You are in science class and want to see if the hot plates were used recently. You place your hand over the hot plate. Without touching the hot plate, your hand feels warmer. Heat is transferred to your hand by Radiation.

You are roasting marshmallows at a campfire. The metal skewer (stick) that you’re cooking your marshmallow on burns your hand because of Conduction.

The answer of 1st blank is Conduction.Lamp heating is due to  Convection.Lamp giving heat is due to radiation.The warm air rises because of Convection. Heat is transferred to your hand by Radiation. The metal skewer (stick) that you’re cooking your marshmallow on burns your hand because of Conduction.

Conduction is defined as a process as a means of which heat is transferred from the hotter end of the body to it's cooler end.Heat flows spontaneously from a body which is hot to a body which is cold.

In the process of conduction,heat flow is within the body and through itself.In solids the conduction of heat is due to the vibrations and collisions of molecules while in liquids and gases it is due to the random motion of the molecules .

When conduction takes place, heat is usually transferred from one molecule to another as they are in direct contact with each other.There are 2 types of conduction:1) steady state conduction 2) transient conduction.According to the type of energy conduction is of three types:

1) heat conduction

2) electrical conduction

3)sound conduction

Snowshoe hares have fur that changes color in fall and spring. This color change is caused by a genetic trait. In the fall, their fur becomes white, the color of winter snow. In the spring, their fur becomes mostly brown, matching their summertime surroundings. This change is not related to the outside temperature. Instead, it is related to change in the lengths of days and nights. The days get shorter in the fall. They get longer again in the spring. But hares don't all have the same genes. Different individuals change color at different times in fall and spring.
