ΔH = m x CP x ΔT
If 980 kJ of energy is added to 6.2 kg of water at 18 C, what is the final temperature of the water?
ΔH = m x CP x [T(final) - T(initial)]
How would heat variability influence cabbage groundsels (picture) on Mount Kenya?
The plants have adapted to contain their heat so it is not released (exothermic) into the surrounding atmosphere
The plants absorb the low heat during the night so that they do not freeze (endothermic)
The plants move their leaves because of the Sun
The plants control the air flow of heat when opening and closing their leaves at night
How would a Hot Spring (picture) in the middle of winter in the Rocky Mountains influence the life within in?
Where there is more heat in a cold environment, there is more accessible, drinking water because it reaches its specific heat
There is more drinkable water because the hot spring heats it up
There are more predators to eat all the prey because of the hot water
The specific heat of snow is different from the specific heat of rain
How would access to drinkable water in a desert climate influence all of life surrounding it? (picture)
Species adapt to an environment in which water is limited because water hits its specific heat and changes form
Species survive using their luck and intelligence of water
Water is randomly displaced throughout a desert due to its specific heat
The specific heat of each animals drives them to drinkable water
How do we measure changes in energy when eating food?
Calories
grams
change in temperature
Specific Heat
How would the exothermic release of heat from sand affect water levels in an environment?
The heat from the sand could make the water reach its specific heat quicker, causing it to evaporate faster
The heat from the water could make the sand reach its specific heat quicker, causing it to evaporate faster
The change in heat from the water absorbs the energy from the surrounding environment
The change in temperature from the sand will decrease the heat absorption of water over time
When there is a loss in heat that is an ___________________ process or reaction.
Endothermic
Exothermic
Heat Capacity
change in temperature
When there is a positive gain in heat energy this is an ___________________ process or reaction.
Exothermic
Endothermic
A transfer of calories
a change in temperature
A high specific heat means....
It takes a shorter amount of time to heat up the substance
It takes a longer amount of time to heat up the substance
It takes the same amount of time to heat up the substance
Time is not affected
A low specific heat means....
A shorter amount of time to heat up a substance
Time is it not affected by specific heat
A longer amount of time to heat up a substance
An equal amount of time to heat up a substance
