3.
Isabella filled a glass with warm water. She measured the temperature, and it was 30°C. She left the glass on a table in a room that was 20°C. A few hours later, she measured the water temperature again, and it was 24°C. Which BEST explains why the water temperature changed?
a)
Energy in the air removed heat from the water.
b)
Heat energy in the water was destroyed by the glass.
c)
Heat energy in the water was transferred to the cooler air.
d)
Energy used by evaporation caused the water temperature to decrease
4.
In an investigation, water in an Erlenmeyer flask is placed on a hot plate. As the water is heated, the cooler, denser water at the surface sinks and pushes the warmer water to the top. What do the arrows in the drawing MOST likely represent?
a)
phase changes
b)
convection currents
c)
electromagnetic radiation
d)
energy transfer by conduction
5.
The BEST example of heat transfer by convection is when

sunlight warms soil.
b)
feeling the heat from a campfire
c)
flames heat up a pan
d)
heat rises in a chimney
6.
Which of the following will absorb heat energy?
a)
two sticks being rubbed together
b)
a piece of wood burning
c)
steel wool rusting
d)
ice cubes melting
7.
Why is covering up with a thick, fluffy blanket a good way to stay warm on a cold night?
a)
The blanket produces heat that warms your body.
b)
The blanket transfers thermal energy from the room to your body.
c)
The blanket decreases the transfer of thermal energy from your body to the air.
d)
The blanket increases the amount of thermal energy that your body produces.
8.

from the ice to the tea
b)
from the tea to the ice
c)
from the pitcher to the tea
d)
from the ice to the pitcher

convection
b)
conduction
c)
radiation
d)
reflection
