a)
126 degrees C
b)
60 degrees F
c)
60 degrees C

7.
What does "ΔH" mean? 
a)
A change in health
b)
A change in heat
c)
A change in height
d)
A change in temperature
8.
What is the equation to find the ΔT of a substance? 
a)
ΔH = m x CP x ΔT
b)
ΔT(initial) + ΔT(final)
c)
ΔT = T(final) - T(initial)
d)
ΔT = T(initial) - T(final)
9.
Why does water heat up faster than sand based on their specific heat(s) and physical states? 
a)
Water has a higher Cp and is a liquid, so it can heat up quickly 
b)
Water has a lower Cp and is a liquid, so it can heat up quickly 
c)
Water heats up faster because its specific heat is lower than sand's Cp
d)
Water has a higher Cp but takes longer to heat up because of its high Cp
10.
What is the equation to find the Heat Capacity and/or Specific Heat of a substance? 
a)
ΔH = m x CP x ΔT
b)
ΔH = m - CP - ΔT
c)
ΔH = m ∕ CP ∕ ΔT
d)
ΔT = ΔT(initial) - ΔT(final)
11.

29 C
b)
8 C
c)
0.008 C
d)
80 C 
13.

How would heat variability influence cabbage groundsels (picture) on Mount Kenya?

a)

The plants have adapted to contain their heat so it is not released (exothermic) into the surrounding atmosphere

b)

The plants absorb the low heat during the night so that they do not freeze (endothermic)

c)

The plants move their leaves because of the Sun

d)

The plants control the air flow of heat when opening and closing their leaves at night

14.

How would a Hot Spring (picture) in the middle of winter in the Rocky Mountains influence the life within in?

a)

Where there is more heat in a cold environment, there is more accessible, drinking water because it reaches its specific heat

b)

There is more drinkable water because the hot spring heats it up

c)

There are more predators to eat all the prey because of the hot water

d)

The specific heat of snow is different from the specific heat of rain

15.

How would access to drinkable water in a desert climate influence all of life surrounding it? (picture)

a)

Species adapt to an environment in which water is limited because water hits its specific heat and changes form

b)

Species survive using their luck and intelligence of water

c)

Water is randomly displaced throughout a desert due to its specific heat

d)

The specific heat of each animals drives them to drinkable water

16.

How do we measure changes in energy when eating food?

a)

Calories

b)

grams

c)

change in temperature

d)

Specific Heat

17.

How would the exothermic release of heat from sand affect water levels in an environment?

a)

The heat from the sand could make the water reach its specific heat quicker, causing it to evaporate faster

b)

The heat from the water could make the sand reach its specific heat quicker, causing it to evaporate faster

c)

The change in heat from the water absorbs the energy from the surrounding environment

d)

The change in temperature from the sand will decrease the heat absorption of water over time
