Matter and Energy EOG Review

In which way are evaporation and condensation similar? 

• Both cause decreases in air temperature. 
• Both cause increases in air temperature. 
• Both are caused by the warming of the atmosphere.
• Both are caused by changes in heat energy. 

Which is an example of a different substance being formed? 

• glass breaking
• metal melting 
• water freezing
• wood burning 

Which is most responsible for the uneven heating of the air in the atmosphere?

• convection

• radiation

• conduction

• condensation

A pot is heated on a stove. Which process causes the metal handle of the pot to also become hot? 

• combustion 
• convection 
• radiation 
• conduction 

If 10 grams of water are added to 5 grams of salt, how much salt water will be made? 

• 2 grams
• 5 grams 
• 10 grams 
• 15 grams

After a rain, a puddle of water remains on a sidewalk. After a day of sunshine, the puddle is gone. Which process is most responsible for the disappearance of the puddle?

• precipitation 
• transpiration
• evaporation
• condensation 

A student notices that an inflated balloon gets larger when it is warmed by a lamp. Which best describes the mass of the balloon as a result of this change? 

• The mass of the balloon increases because the size of the balloon has increased. 
• The mass of the balloon increases because the temperature of the balloon has increased.  
• The mass of the balloon stays the same because the gas inside the balloon still has the same mass after it warms up. 
• The mass of the balloon stays the same because warming decreases the mass enough to cancel out the effect of increasing the size.  

People sitting around a campfire are able to feel the heat from the fire. How are the people able to feel the heat from the fire without touching the fire? 

• The heat from the fire travels through the ground and heats the ground around the people.  
• The heat from the fire is conducted through air molecules to the people. 
• The heat from the fire rises in the air and then settles around the people. 
• The heat from the fire radiates from the fire to the people. 

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

• convection 
• evaporation 
• radiation 
• conduction 

What must occur before clouds can form? 

• Water vapor must get warmer. 
• Water vapor must lose heat energy.
• Precipitation must begin to fall and run off.
• Transpiration must add water vapor to the atmosphere.
