Ch 7 States of Matter

Question 1

Smaller alveoli have more or less surfactant than larger alveoli?

Answer 1

Smaller has more because it needs more because of the higher surface tension.

Question 2

What is latent heat of vaporization?

Answer 2

number of calories (J) to convert 1g of liquid to vapor without a temperature change in the liquid

Question 3

What is boiling point?

Answer 3

The temperature at which a liquid’s vapor pressure equals atmospheric pressure.

Question 4

What is specific heat?

Answer 4

Amount of heat required to increase the temperature of 1 gram of substance by 1 degree Celsius.

Question 5

What is critical temperature?

Answer 5

The highest temperature is where a gas can exist as a liquid. Once past this temp, the liquid becomes a gas and no amount of pressure will turn it back to a liquid.

Question 6

What is the heat of vaporization (not latent)?

Answer 6

Number of calories required to vaporize 1mL of liquid.

Question 7

Define critical temperature

Answer 7

Minimum amount of pressure is required to convert a gas to a liquid at its critical temp.

Question 8

What is an adiabatic process?

Answer 8

A process that occurs without gain or loss of energy.
