Question 37

37.

Storm windows were used in the past to prevent heat from leaving the inside of the house in the winter. They weren’t very efficient, because the space between the two panes of glass allowed convection current to take heat out even more. The new energy efficient windows prevent this from happening by preventing convection from happening. Krypton gas fills the space between the panes of glass because it is a ...

A

B

C

D

Question 19

19.

Because your senses can easily be fooled, thermometers were developed, because they are more reliable.
The earliest thermometers contained a glass bottle with a long glass tube for the liquid to rise and fall. An
important part was missing though. It was the ...

A

B

C

Question 20

20.

Estimating temperature, without using a thermal sensing device, is something that we do automatically.

Question 21

21.

When air is heated inside a balloon, the air makes the balloon rise. This happens because – compared to the
air outside the balloon, the heated air is ...

A

B

C

Question 22

22.

When a substance is heated the particles gain energy and spread out, creating more volume (spaces between the particles). So what about the mass of the substance? What happens to the mass of a substance
