An ideal gas held at constant pressure has its temperature changed by a factor of 1.72x. By what factor does its volume increase or decrease?

An ideal gas at 14.7 °C and a pressure of 2.92 x 105 Pa occupies a volume of 3.40 m³. (a) How many moles of gas are present? (b) If the volume is raised to 5.33 m³ and the temperature raised to 31.0 °C, what will be the pressure of the gas? (a) Number Units (b) Number Units

A bubble of air is rising from the sea floor, from a depth of about 500 m. At this depth the pressure is 5.1*106 Pa (about 50.3 atm) and is at a temperature of about 7.0° C. It rises to the surface with the atmosphere, at a temperature of 20° C. If the bubble is observed to have a volume of 4 cm³ at the surface, what was its volume at the sea floor? Assume the number of moles of gas in the bubble is constant. B.

The absolute pressure inside an oxygen tank is P=100kPa, the temperature is 27°C, and the mass is m=3.0 kg.  Assume the oxygen behaves as an ideal gas. The gas constant of oxygen is R=0.2598 kPa·m3/kg·K. The temperature relation is T(K)=T(°C)+273. Determine the volume of  oxygen tank ______ m3

A gas condensed in a cylinder with a nozzle is initially at p_1=2000 Pa, V_1= 2.0 l, and t_1=300 K. a) If the volume decreases to 0.50 L while the temperature remains low, what is the new pressure?b) If in a) the temperature increases to 400 K when the volume changes, what will be the new pressure?

The volume of an automobile tire is 2.5 × 10−2m3 . the pressure of the air in the tire is  3.3 atm and the temperature is 17C ◦ . what is is the mass of air in grams ? The mean molecular mass of air is 29g.                                      1 atm = 1.01  × 105 Pa ;  Calculate to 2 decimals.

The density of helium gas at 0.0◦C is0.16 kg/m3kg/m3. The temperature is thenraised to 102 ◦C, but the pressure is kept constant.Assuming that helium is an ideal gas, calculate the new density of the gas.Answer in units of kg/m3.

An automobile tire is inflated with air originally at 10.0°C and normal atmospheric pressure. During the process, the air is compressed to 27.0% of its original volume and the temperature is increased to 38.0°C. (a) What is the tire pressure in pascals? Use the ideal gas law to find the pressure inside the tire from its volume and temperature. Pa(b) After the car is driven at high speed, the tire's air temperature rises to 85.0°C and the tire's interior volume increases by 3.00%. What is the new tire pressure (absolute) in pascals?

A balloon is filled with helium gas at atmospheric pressure (1 atm) until its volume is 800 m³. The helium gas is then transferred to cylinders that have a volume of 2.3 m³ at a pres- sure of 13.3 atm. Calculate the number of cylinders used. Assume that the temperature of the helium gas remains constant. (1 atm = 1.013 × 105 Pa).
