- An airtight dispenser for drinking water is 25 cm × 10 cm in horizontal dimensions and 20 cm tall. It has a tap of negligible volume that opens at the level of the bottom of the dispenser. Initially, it contains Water to a level 3.0 cm from the top and air at the ambient pressure, 1.00 atm, from there to the top. When the tap is opened, water will flow out until the gauge pressure at the bottom of dispenser, and thus at the opening of the tap, is 0. What volume of water flows out? Assume the temperature is constant, the dispenser is perfectly rigid, and the water has a constant density of 1000 kg/m3.One of a dilute diatomic gas occupying a volume of 10.00 L expands against a constant pressure of 2.000 atm when it is slowly heated. If the temperature of the gas rises by 10.00 K and 400.0 J of heat are added in the process, what is its final volume?One mole of a dilute diatomic gas occupying a volume of 10.00 L expands against a constant pressure of 2.000 atm when it is slowly heated. If the temperature of the gas rises by 10.00 K and 400.0 J of heat are added in the process, what is its final volume?
- The initial pressure and volume are 80 kPa and 0.35 m3, respectively. The final pressure and volume are 170 kPa and 0.85 m3. How much work was done by the gas (in joules) in this process?How much work is done on the gas in the process as shown, in Joules? Vf = 85 cm3. (1.00 cm3 = 1.00×10-6 m3, 1.00 kPa = 1.00×103 Pa.)The internal energy of a system increases by 1350 J when the system absorbs 1150 J of heat energy at a constant pressure of 1.01 X 105 Pa. By how much does the volume (m3) of the system change?
- One mole of an ideal gas does 1700 J of work as it expands isothermally to a final pressure of 1.00 × 105 Pa and volume of 0.039 m3. What was the initial volume of the gas, in cubic meters?How much work is done on the gas in the process as shown, in Joules? Vf = 94 cm3. (1.00 cm3 = 1.00×10-6 m3, 1.00 kPa = 1.00×103 Pa.) Your answer needs to have 2 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.flow to the surroundings, including the container. 20. An ideal gas is slowly compressed at a constant pressure of 2.0 atm from 10.0 L to 2.0 L. (In this process, some heat flows out of the gas and the temperature drops.) Heat is then added to the gas, holding the volume constant, and the pressure and temperature are allowed to rise (line DA) until the temperature reaches its original value (TA = TB). Calculate (a) the total work done by the gas in the process BDA, and (b) the total heat flow into the gas. PB PAT Isovolumetric D I 0 2 A Isothermal Isobaric 4 6 8 B 10 V (L)
- A closed container of volume V = 12 liters holds a mass m, = 0.858 kg of oxygen. It is known that the mass of a liter of oxygen at atmospheric pressure is mą = 0.0015 kg at the same temperature. What is the pressure in the con- tainer?A tire with an inner volume of 0.025 m³ is filled with air at a gauge pressure of 36psi. If the tire valve is opened to the atmosphere, what volume outside of the tire does the escaping air occupy? Some air remains within the tire occupying the original volume, but now that remaining air is at atmospheric pressure. Assume the temperature of the air does not change.1.00 mol of an ideal gas is compressed isobarically from a volume of 40.0 L to avolume of 30.0 L at a pressure of 110 kPa. How much work is done?
