Use the definition for coefficient of volume expansion γ = -( δv/vδθ) to show that the change in density δρ of a substance when temperature changes by δθ is given by δρ = γρ δθ. what is the fractional change in the density of mercury when temperature changes for 30 degree c to -10 degree c. the density of mercury at 30 degree c is 13600 kgm^-3.

Air enters a compressor operating at steady state at 1.05 bar, 300 k, with a volumetric flow rate of 93 m3/min and exits at 12 bar, 400 k. heat transfer occurs at a rate of 15.5 kw from the compressor to its surroundings. assuming the ideal gas model for air neglecting kinetic potential energy effects, determine the power in put in kw.

Light from the sun reaches the earth in 8.3 minutes. the velocity is 3.00 x 10^8 m/s. how far is earth from the sun? i know how to get to d = (3 x 10^8 m/s)(498 sec). i just don't know how to get from there to the answer being 1.5 x 10^11 m.
