If the temperature of an ideal gas is raised from 30 °C to 210 °C, how many times faster is the new average (ms) speed of the gas molecules? timesYou happen to come across a piece of metal that has a density of p = 7.43 g/cm³ when the temperature is To = 45.0 °C. If the metal is cooled to a temperature of T = 0.00 °C, does the density change? No, because as the volume changes so does the mass. No, density does not depend on temperature. Yes, since the metal contracts and the mass is constant, the density will increase. Yes, the density will decrease since the volume changes. Calculate the density of the piece of metal at this temperature, p1. The coefficient of volume expansion for this piece of metal is ß = 8.43 x 10-s 1°°C.
