In the morning, a paintball pressure tank is at 306 atm. The weather heats up over the course of the day, and by 3 PM, the outside temperature is roasting at 38.5°C, and the pressure inside the tank is 324 atm. What was the temperature (in degree Celsius) in the morning?

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 pot of water is boiling under one atmosphere of pressure. Assume that heat enters the pot only through its bottom, which is copper and rests on a heating element. In two minutes, the mass of water boiled away is m = 2.5 kg. The radius of the pot bottom is R = 8.0 cm and the thickness is L = 1.0 mm. What is the temperature of the heating element in contact with the pot? TE = Number i Units

A Goodyear blimp typically contains 5300 m of helium (He) at an absolute pressure of 1.10 x 10 Pa. The temperature of the helium is 275 K. What is the mass (in kg) of the helium in the blimp? Number Units the tolerance is +/-2%

On a nice winter day at the South Pole, the temperature rises to  −33°F.  What is the approximate temperature in degrees Celsius? °C

A machinist wishes to insert an iron rod with a diameter of 9 mm into a hole with a diameter of 8.998 mm. By how much would the machinist have to lower the temperature (in Celsius) of the rod to make it fit in the hole?

An apartment has the dimensions 16 m by 8 m by 5 m. The temperature is 30°C, and the relative humidity is 51 percent. What is the total mass (in kg) of water vapor in the air in the apartment?

the density of lead is 11.0 g/cc at 4°C. What is the density of lead in pounds per cubic feet at this temperature?

The mass of a hot-air balloon and its cargo (not including the air inside) is 160 kg. The air outside is at 10.0°C and 101 kPa. The volume of the balloon is 550 m3. To what temperature must the air in the balloon be warmed before the balloon will lift off? (Air density at 10.0°C is 1.244 kg/m3.) K=??

Two students in a physics lab have to construct a constant-volume gas thermometer as part of their end of year project. They use liquid nitrogen (-196°C) and boiling pentane (36.1°C) to calibrate the thermometer. The corresponding values of pressure are 0.420 atm and 1.325 atm. The students plot a pressure versus temperature graph with pressure on the y-axis and temperature on the x-axis. (a) Determine the y intercept and slope of the linear graph that relates the pressure to the temperature. slope     atm/°C y intercept     atm b) What value of absolute zero do the students get from this calibration?°C(c) What pressure readings would this thermometer give for the freezing and boiling points of water? freezing point     atm boiling point     atm
