Why does a balloon shrink in size when moved from a warm store to a cold environment, according to Charles’ Law?

• Because pressure increases as temperature decreases.

• Because volume increases as temperature decreases.

• Because volume decreases as temperature decreases.

• Because pressure and volume both increase.

Which of the following best represents the relationship between volume and temperature at constant pressure, as described by Charles’ Law? (choose all that apply)

• Direct relationship

• inverse relationship

• straight line with positive slope

• straight line with negative slope
