If a hot rod is placed into cold water, what will happen?
The temperature of the rod and water will cool down
The temperature of the rod and water will both increase
The water will transfer coldness to the rod
The rod will cool down and the water will heat up
What eventually happens as heat is transferred?
Convection will continue
Conduction will continue
Heat will continue to be transferred
Equilibrium is reached where both objects become the same temperature
Copper wires are often coated with rubber. Why?
Rubber is a great conductor.
Rubber protects us from electrical shock as it allows electricity to flow through it easily
Rubber protects us from electrical shock as it slows and resists the flow of electricity
All are true.
If you pour hot water into an aluminum cup, what will happen?
Convection will occur
Radiation will occur between the water, cup and your hand
heat will be conducted from the water through the cup to your hand
heat will be conducted from your hand to the cup and to the water
What will happen to the ice water if it sits in the classroom for 24 hours?
Temperature of the water will decrease as it loses thermal energy
Temperature of the water will increase as it loses thermal energy
The temperature of the water will decrease as it gains thermal energy
Temperature of the water will increase as it gains thermal energy
Why do our hands feel cold when we hold ice cubes?
The coldness from the ice cubes moves into our hands.
We lose heat in our hands when it transfers to the ice cubes.
The cold ice cubes transfers cool molecules to our hands.
