Suppose you have a closed rigid container of air at 20 Celsius on the surface of the Earth. We change the temperature of the container to 48 Celsius, leaving it closed, and read a pressure gauge attached to the container. Initially the reading was 101 KPa (kilopascals, or 1000 N/m2). What is the new reading? Give your answer in KP

How many cubic meters of helium are required to lift a light balloon with a 400-kg payload to a height of 8 000 m? Take Hc = 0.179 kg/m3. Assume the balloon maintains a constant volume and the density of air decreases with the altitude z according to the expression pair = 0e-z/8 000, where z is in meters and 0 = 1.20 kg/m3 is the density of air at sea level.

The ideal gas law describes the state of a hypothetical ideal gas, i.e., PV = nRT where P is the pressure in Pascal, V is the volume in liters L, R is the ideal gas constant, T is the temperature in kelvin K, and n is the amount of substance. Suppose a researcher has n = 0.654 moles of neon gas. He observed that T and V are increasing at rates of 3 K/min and 2 L/min, respectively, using the fixed gas constant R= 8.31 J/K.mol, find the rate at which the pressure is changing when V = 12.3 L and T = 447K.
Suppose you have a closed rigid container of air at 20 Celsius on the surface of the Earth.
