A sealed gas cylinder on the back of an open truck experiences a temperature change from -19.4 °C to 38.8 °C as it is driven from North Dakota to Arizona. If the pressure gauge on the tank reads 133.9 atm in North Dakota, what will the gauge read in Arizona, in atm?

You happen to come across a piece of metal that has a density of p 8.12 g/cm3 when the temperature is To = 42.5 °C. If the metal is cooled to a temperature of T1 0.00 °C, does the density change? Yes, the density will decrease since the volume changes. Yes, since the metal contracts and the mass is constant, the density will increase. No, because as the volume changes so does the mass. No, density does not depend on temperature. Calculate the density of the piece of metal at this temperature, P1. The coefficient of volume expansion for this piece of metal is B = 7.62 x 10-5 1/°C. -0.0263 Pi = g/cm3 Incorrect

A helium-filled balloon has volume 3.8_m³, temperature 25.4°C, and pressure 1 atm while at sea level. If the balloon rises to 27000 ft, where the temperature is 3.5°C and the pressure is about 1/3 of its sea-level value, then find the new volume of the balloon. 10.56.m3 20.65_m3 18.71 m3 19.31 m3 А. D. 7.678 m3 20.74 m3 В. Е. С. F.

The volume of a gas at 20°C is 100cm3 at normal pressure. If it is heated to 100°C, its volume becomes 125cm3 at the same pressure, then volume coefficients of the gas (at normal pressure) is? a) 0.0033/°C b) 0.0025/°C c) 0.0030/°C d) 0.0021/°C
