What is the volume occupied by 2.50 moles of air at 0°C and 760 torr? 89.6 m³ 22.4 m³ 44.8 m³ 0.0560 m³ 0.0224 m³

63.0 L of oxygen at 21.0°C and an absolute pressure of 2.55atm are compressed to 38.3L and at the same time, the temperature is raised to 53.0°C. What will the new pressure be? P= atm

0.52 mol of argon gas is admitted to an evacuated 3.00 liter (3.00 × 10-3 m3) container at 20.0°C. The gas then undergoes an isobaric process to a temperature of 260°C. What is the final volume of the gas, in liters? Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

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

If 23.5 moles of an ideal gas occupies 0.0465 cubic meters at 14.5 °C, what is the pressure of the gas? pressure: Pa

A gas under constant pressure has a volume of 30.57m^3 and a temperature of 59.0 K. A change in temperature caused the volume to change to 121.14m^3. Based on the relationship between volume and temperature, what must have happened to the temperature? A- Temperature decreased B- Temperature increased C- Temperature stayed the same D- Temperature trend can not be determined

A hot air balloon uses the principle of buoyancy to create lift. By making the air inside the balloon less dense then the surrounding air, the balloon is able to lift objects many times its own weight. A large hot air balloon has a maximum balloon volume of 2090 m3. a.  If the air temperature in the balloon is 54 °C, how much additional mass, in kilograms, can the balloon lift? Assume the molar mass of air is 28.97 g/mol, the air density is 1.20 kg/m3, and the air pressure is 1 atm.

A fixed amount of a particular ideal gas at 20°C and a pressure of 1.75 × 105 Pa occupies a volume of 2.60 m3. If the volume is increased to 4.2 m³ and the temperature is raised to 27.0°C, what will be the new pressure (in Pa) of the gas? Pa
