Monday Practice

On a hot summer day, a student dropped an ice cube onto a park bench. Within minutes, the ice cube melted. Which best describes the process the student observed?

• radiation

• combustion

• conduction

• convection

A cold metal spoon is placed in a bowl of hot soup. Which best describes how the spoon is affected?

• The heat from the soup does not affect the temperature of the spoon.

• The heat from the soup is conducted through the spoon, making the spoon warmer.

• The cold air in the room radiates into the soup, cooling it, and keeping the spoon cool.

• The cold from the spoon is conducted into the soup, causing the soup to cool to the same temperature as the spoon.T

Mary stands in a swimming pool and notices that the water around her feet is a lot cooler than the water near the surface. Which process causes this difference in temperature?

• convection

• evaporation

• radiation

• conduction

Which is an example of conduction?

• Steam is rising from a cup of hot coffee.

• A hot biscuit is warming the plate it is on.

• The sun is shining through a window and warming a table.

Which best explains how ice melts in a person’s hand?

• The heat from a person’s hand transfers by radiation to the ice, causing it to melt.

• The heat from a person’s hand transfers by conduction to the ice, causing it to melt.

• The cool temperature of the ice transfers by radiation to a person’s hand, cooling it off.

• The cool temperature of the ice transfers by conduction to a person’s hand, cooling it off.

Tina is boiling water in a metal pot for a weather experiment. What is most likely the reason she would need to use a pot holder for moving the metal pot?

• Radiation causes the pot to be hot.

• Conduction causes the pot to be hot.

• Convection causes the pot to be hot.

• Transpiration causes the pot to be hot.

A boy touches a stove and gets burned. What transfer of heat caused his hand to get burned?

• radiation

• conduction

• convection

• combustion
