Mass of empty Calorimeter is 7.73g, mass of Calorimeter + water is 46.875g, mass of water is 39.145g, mass of metal is 6.354g, initial temperature of water is 20 degrees Celsius, initial temperature of metal is 100 degrees Celsius, final temperature of Calorimeter is 21.5 degrees Celsius, T(T-final - T-initial) is 78.5 degrees Celsius, calculate the q-Calorimeter.

A shipment from Earth to Mars contains a 50 gallon​ [gal] tank filled with an ideal gas. The molecular weight of the ideal gas is 15.9 grams per mole​ [g/mol]. NASA tells the astronauts on Mars that the tank and gas combined had an initial total mass of 5 kilograms​ [kg] and the pressure was 3 atmospheres​ [atm] before it left the Earth. During the​ trip, the temperature was kept constant at 20 degrees Celsius ​[°​C]. When it arrives on​ Mars, the astronauts check the sensors and discover the pressure is 2.2 atmospheres​ [atm] and the temperature is 20 degrees Celsius ​[°​C]. Based on this​ information, the astronauts determine that some of the gas leaked during shipment. Determine how much gas leaked from the tank in units of grams​ [g]. Gravity on Mars​ = 3.71 meters per second squared​[m/s2​].

A fixed amount of an ideal gas is initially at a temperature of 25 °C. To what temperature you need to cool it down after you compress it to half of its volume if you want to keep the pressure constant? Give your answer in units of [Kelvin]

When the temperature of a coin is raised by 82 °F, the coin's diameter increases by 2.20 x 10-5 m. If the original diameter is 2.15 x 10-2 m, find the coefficient of linear expansion.

At time t = 0, a vessel contains a mixture of 10. kg of water and an unknown mass of ice in equilibrium at 0°C. The temperature of the mixture is measured over a period of an hour, with the following results: During the first 50. min, the mixture remains at 0°C; from 50. min to 60. min, the temperature increases steadily from 0°C to 2.0°C. Neglecting the heat capacity of the vessel, determine the mass of ice that was initially placed in it. Assume a constant power input to the container.

A high-pressure gas cylinder contains 50 L of toxic gas at a pressure of 1.5.107 N/m² and a temperature of 23 °C. Its valve leaks after the cylinder is dropped. The cylinder is cooled to dry ice temperature -78.5 °C to reduce the leak rate and pressure so that it can be safely repaired. (a) What is the final pressure in the tank, assuming a negligible amount of gas leaks while being cooled and that there is no phase change? P: 9837079 Pa (b) What is the final pressure if one-tenth of the gas escapes? P 8853371 Pa (c) To what temperature must the tank be cooled to reduce the pressure to 1.00 atm (assuming the gas does not change phase and that there is no leakage during cooling)? T: 200.331 K (d) Does cooling the tank appear to be a practical solution to bring the pressure down and reduce the leak? Assume N, N2. Take into account the values calculatesd in parts (a) through (c). No ! No, that's only partially correct
