______ is the amount of energy necessary to raise the temperature of one gram of substance by 1° C or 1 K.
Specific heat is the amount of energy necessary to raise the temperature of one gram of substance by 1° C or 1 K.
Heat of transformation is the amount of energy required for a phase change of a substance.
What is the formula for heat of transformation?
Q = mHL
Where:
Q = heat transferred during the phase change
m = mass
HL = latent heat or heat of transformation
Work in regards to expansion or compression of a gas is calculated using the which formula?
W = -PΔV
Work = - (pressure) x (change in volume)
Define intensity in terms of power and separately in terms of energy.
I = P/A = (E/t)/A
Intensity of light and sound waves is perceived as ______ and _______, respectively.
Intensity of light and sound waves is perceived as brightness and loudness.
What is the equation for Absolute Pressure?
(Hint: The absolute pressure is the sum of all pressures at a certain point within a fluid)
Ptotal = P0 + ρ g h
Absolute pressure = (pressure at the surface of the fluid) + (pressure due to the fluid's weight)
