200
You are taking a bath. When the water in the tub gets too cold, you add some hot water to make it warmer. What type of heat transfer is happening?
Convection
200
What is the definition of kinetic energy?
The energy that an object has due to its mass and motion
200
Which units do we use to represent the density of an object?
g/cm3
200
Give an example of sublimation.
Dry ice
200
Name two ways that boiling and evaporation are different
Bubbles, heat is needed, speed, etc
300
What happens to the density of water when it is boiling in a pot?
The density of the hot water at the bottom of the pot decreases, and circulates with the colder water at the top of the pot, which is more dense.
300
When does a spring have the most potential energy?
When it is stretched out
300
If a solid object is taken from Earth far into space, which of the following measurements of the object will change most?
Its weight
300
What are the five "WAYS" that matter can change its state?
Melting, Freezing, Sublimation, Condensation, Vaporization
300
What is the process called that allows clouds to form?
Vaporization or Evaporation
400
You put one test tube of 50°C liquid and one test tube of 10°C liquid into a 20°C water. In which direction will the heat transfer?
From hot to cold, from the test tube to the bowl
400
HOW is solar energy converted into electricity?
Using solar panels
400
How do you find the volume of a cube?
Length x width x height
400
Describe the energy of the particles in a solid, a liquid, and a gas
In a solid, they have little energy and can only vibrate and are organized; in a liquid they are close together and can flow, in a gas the have the most energy and can move all around
400
What is the change of state that causes clouds to become rain?
Condensation
500
The surface of a heated metal object
measures 120°C. It is dropped into a
bucket filled with water measuring 10°C. What will happen?
The water and metal will adjust to the same temperature between 10°C and 120°C.
