lost mass
How do the type of matter, the mass of matter, and the temperature change of matter affect the amount of heat energy transferred by a sample of matter within a closed system?
The type of matter does not affect the heat energy transferred.
The mass of matter affects the heat energy transferred.
The temperature change of matter does not affect the heat energy transferred.
All of the above factors affect the heat energy transferred.
Make a claim, using quantitative data as evidence, about the relationship between the type of metal and the amount of energy transferred. (Remember that, in this investigation, the change in temperature of the water is directly related to the amount of energy transferred). All three metals must be included in your claim.
The type of metal does not affect the amount of energy transferred.
Different metals transfer different amounts of energy, as evidenced by varying temperature changes in water.
All metals transfer the same amount of energy, resulting in identical temperature changes in water.
The amount of energy transferred is inversely proportional to the type of metal used.
What is the purpose of the investigation involving changing the mass of heated metal washers placed in room temperature water?
To determine if the mass of the washers affects the amount of energy transferred.
To measure the boiling point of water using metal washers.
To find the specific heat capacity of the metal washers.
To observe the cooling rate of metal washers in water.
Which piece of evidence collected was evidence of energy transferred?
the starting temperature of the metal
the final temperature of the metal
the mass of the metal
the change in temperature of the water
What happens to the particles in a substance when it is cooled?
They move faster
They move slower
They expand
They disappear
In an experiment, a metal rod is heated and then placed in cold water. What is the expected outcome?
The rod will cool down and the water will heat up
The rod will heat up and the water will cool down
Both the rod and water will heat up
Both the rod and water will cool down
Which of the following best describes the process of conduction?
Transfer of heat through a fluid
Transfer of heat through electromagnetic waves
Transfer of heat through direct contact
Transfer of heat through empty space
What is the primary reason ice melts when placed in a warm room?
The ice absorbs heat from the surroundings
The ice releases cold into the surroundings
The ice molecules contract
The ice molecules disappear
During an experiment, a student observes that a metal ball expands when heated. What scientific principle does this demonstrate?
Conservation of mass

Conduction
Evaporation
Which of the following materials is the best conductor of heat?

Plastic
Copper
Glass
A scientist measures the temperature change of water when a hot object is submerged in it. What is this an example of?
Chemical reaction
Thermal equilibrium
Heat transfer
Phase change
What happens to the density of a gas when it is cooled?
It increases
It decreases
It remains the same
It becomes zero
In a lab experiment, a student places a thermometer in a beaker of water and heats it. What is the student likely measuring?
The boiling point of water
The rate of evaporation
The increase in temperature
The decrease in temperature
