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
Which best explains why a hot air balloon floats?
The heated air expands to fill the balloon. The air in the balloon is now lighter than the surrounding air, causing the balloon to rise.
The heated air expands to fill the balloon. The air in the balloon is now heavier than the surrounding air, causing the balloon to rise.
The heated air contracts to fill the balloon. The air in the balloon is now denser than the surrounding air, causing the balloon to rise.
The heated air contracts to fill the balloon. The air in the balloon is now lighter than the surrounding air, causing the balloon to rise.
James measured the temperature outside his house everyday for 2 months. He observed that on days the sky was mostly cloudy, the temperature was an average of 9 degrees cooler than days the sky was mostly sunny. Which best describes the reason for this pattern?
The clouds blocked radiation from the sun, causing cooler temperatures.
The clouds blocked conduction from the sun, causing cooler temperatures.
The clouds allowed more radiation from the sun to reach the Earth’s surface.
The clouds allowed more conduction from the sun to reach the Earth’s surface.
A small ice cube at a temperature of 0°C is dropped into a glass of water at 28°C and melts. What is the temperature of the water in the glass just after the ice cube melts?
0°C
between 0°C and 28°C
28°C
greater than 28°C
Which best explains how convected heat causes a hot air balloon to stay in the air?
The heat is falling and replacing cooler air.
The heat is produced from the rising of air currents.
The heat is absorbed through the balloon from the sun.
The heat is rising and circulating, causing the balloon to stay up in the air.
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 pot of water is placed on a stove. The water begins to boil rapidly. Which explains why the water is boiling faster?
The cooler water is rising in the pot to replace the warmer water on top through the process of radiation.
The warm water is rising in the pot to replace the cooler water on top through the process of radiation.
The warm water is rising in the pot to replace the cooler water on top through the process of convection.
The cooler water is rising in the pot to replace the warmer water on top through the process of convection.
A boy touches a stove and gets burned. What transfer of heat caused his hand to get burned?
radiation
conduction
convection
combustion
Which is the best choice for the handle of a frying pan?
Metal, because it conducts heat.
Wood, because it conducts heat.

Which substance will conduct the least amount of heat?
glass
copper
plastic
aluminum
Ice cubes are placed in a glass of water that is at room temperature. Which statement best describes the temperature of the water after 10 minutes?
The temperature decreases because some of the water’s heat is lost to the ice.
The temperature decreases because some of the ice’s heat is lost to the water.
The temperature increases because some of the coolness of the water is absorbed by the ice.
The temperature increases because some of the coolness of the ice is absorbed by the water.
