Match the descriptions to the terms in the list below. Assume nothing: choices may be used more than once, or not at all. More than one listed answer may be correct.

Select the equations used when solving the above problem:  (The original problem: A concrete cube with side 2.00 m and emissivity 0.55 is heated to T.  If the ambient temperature is 25.0°C, what net power (in kW) does the cube radiate?  

An underground gasoline tank can hold {V} gallons of gasoline at 52.0°F.  The tank is being filled on a hot day by a truck when the outdoor temperature is {T}°F.  How many gallons of gasoline from the truck can be poured into the tank? Assume the temperature of the gasoline quickly cools from {T}°F to 52.0°F upon entering the tank. (The coefficient of volume expansion for gasoline is 9.6  10-4 (°C)−1.)

For a physics experiment, a solid cube is suspended from a spring scale. The gravitational force exerted on the cube is 0.714 N as measured when the object is suspended from a spring scale. When the suspended cube is submerged in water (ρ = 1000 kg/m3), the scale reads 0.450 N.   What is the mass of the object in g (grams)?
