Heat can be subtracted by conduction to another object or system at a lower temperature (requires contact between the objects or systems) or by radiating heat to another object or system (does not require contact - just a clear path for the radiated heat to move through)

What has to be added to a substance to cause a phase change?
Heat energy must be added to or subtracted from a substance to cause a phase change.
Hurricanes are an efficient way to?
Redistribute heat from one area to another.
One way to warm air without adding heat is to?
Compress it, such as by inflating a tire
Should water content or LOD be subtracted from potency?
Whichever is higher in value should be subtracted
Capacity ratio of a heat exchanger?
It is the ratio of (mdot*Cp)min/(mdot*Cp)max where the heat exchanger contains two fluids for which the mdot*Cp should be calculated for each to determine which one is greater. by doing so one can define the ability of one fluid to carry thermal/heat energy with respect to the other. so this is a way of saying how well can heat be transferred and so how effective is the heat exchanger
When heat is added or subtracted is called?
heat treatment
What does the heating and cooling of molecules do?
Changes the movement of the molecules as the heat is added and subtracted.
What is 1 subtracted by 3 and one half?
1 subtracted by 3 and one half = -2
What is 40 and one-fourth subtracted by 38 and one half?
2

How are heat and conduction related?
Conduction is one way that heat spreads.
What fraction subtracted from what fraction equals 7?
1.5 subtracted from 8.5 is one of infinitely many possible answers.
What does the addition or subtraction of heat have to do with whether or not a substance is a solid liquid gas or plasma?
When heat is added or subtracted, it chemically changes the substance into a different type of matter.
What is one subtracted by negative three?
