A vessel has a volume of 0.75 m3 and contains a mixture of air and carbon dioxide at a pressure of 200 kPa and a temperature of 27°C. If the mass of air present is 0.5 kg determine (a) the partial pressure of each gas, and (b) the mass of carbon dioxide. Assume the characteristic gas constant for air to be 287 J/(kg K) and for carbon dioxide 184 J/(kg K). A mass of gas occupies a volume of 0.02 m3 when its pressure is 150 kPa and its temperature is 17°C. If the gas is compressed until its pressure is 500 kPa and its temperature is 57°C, determine (a) the volume it will occupy and (b) its mass, if the characteristic gas constant for the gas is 205 J/(kg K). Calculate the heat energy required to convert 10 kg of ice initially at -30 °C completely into water at 0 °C. Assume the specific heat capacity of ice is 2.1 kJ/(kg °C) and the specific latent heat of fusion of ice is 335 kJ/kg. Some copper, having a mass of 20 kg, cools from a temperature of 120 °C to 70 °C. If the specific heat capacity of copper is 390 J/(kg°C), how much heat energy is lost by the copper? . A platinum resistance thermometer has a resistance of 100 2 at 0 °C. When measuring the temperature of a heat process a resistance value of 177 2 is measured using a Wheatstone bridge. Given that the temperature coefficient of resistance of platinum is 0.0038/°C, determine the temperature of the heat process, correct to the nearest degree.
