Look at the image to the left.

Which of the items is probably the worst at conducting thermal energy?

• A. the ceramic plate

• B. the glass

• C. the metal pot

• D. the pot holder

Look at the image to the left.

What does the pot holder do that makes it poor at conducting thermal energy?

• It heats things up.

• It cools things down.

• It slows heat transfer.

• It speeds up heat transfer.

Look at the image to the left.

What physical property of the matter of the pot holder makes it a poor conductor of thermal energy?

• It oxidizes rapidly.

• It has an orderly molecular structure.

• It has a disorderly molecular structure.

• It is green.

Amy wants to cook a large batch of tomato soup for her family for dinner. But, she has a lot of pots to choose from, each made from different materials. She decides to use the pot that will cook the soup the fastest, so she conducts a quick experiment to see which pot she should use. She places each of the pots on a hot plate. Then she then adds 200 ml of 25° C water to each pot. She waits for each pot to boil, then records the order each pot boiled in the data table below.

What is the best conclusion from this experiment?

• Copper conducts heat the best.

• Iron is the worst conductor of heat.

• Stainless steel conducts heat the best.

• Aluminum is the worst conductor of heat.

Amy uses the pot to make a large batch of tomato soup for her family for dinner. Once it's ready, she selects the pot holder to put underneath the pot before putting it on the table.

Why did Amy choose to put the potholder underneath the pot before putting it on the table?

• The potholder will absorb less heat from the pot than the table will.

• The pot holder will cool down the pot so you can put it on the table.

• The table will absorb less heat from the pot than the table will.

• The pot holder is a good decoration for the table.

The solid sample shown below is dropped into the beaker containing a liquid sample. After the interaction, the combination gets warm and the mass of the combined samples is found to be 30 g.

The law of conservation of mass states that

• matter can be created or destroyed during an interaction.

• matter can be created during chemical changes, but not during physical changes.

• matter can be destroyed during chemical changes, but not during physical changes.

• matter cannot be created or destroyed during an interaction.

The solid sample shown below is dropped into the beaker containing a liquid sample. After the interaction, the combination gets warm and the mass of the combined samples is found to be 30 g.

This experiment most likely involved

• the destruction of matter

• a chemical change

• the creation of new matter

• a physical change

The solid sample shown below is dropped into the beaker containing a liquid sample. After the interaction, the combination gets warm and the mass of the combined samples is found to be 30 g.

Which of these observations accurately supports your answer to #7?

• The volume of the beaker increased after the interaction.

• The substances released heat during the interaction.

• The mass of the substances did not change during the interaction.

• The color of the substances changed after the interaction.

The solid sample shown below is dropped into the beaker containing a liquid sample. After the interaction, the combination gets warm and the mass of the combined samples is found to be 30 g.

What is the likely reason that the recorded mass at the end of the experiment is not what the researchers would have expected?

• The mass appeared to increase, this is likely because new matter was created during the interaction.

• The mass appeared to decrease, this is likely because some matter was destroyed during the interaction.

• The mass appeared to decrease, this is likely because of a chemical reaction that changed some of the matter into gas, which escaped the beaker.

• The mass appeared to increase, this is likely because of a physical change as the solid sample spontaneously evaporation.
