Some scientists believe that coronavirus (Covid-19) can not tolerate high temperatures. They say that keeping the food in hot water (above 70 °C) for at least 5 minutes will make the food safer compared to the uncooked food. a) Calculate the heat, in kilojoules, needed to prepare 10 L of hot liquid water at 75 °C if the initial temperature of water is 20 °C? b) A minimum of how many grams of isooctane (C3H18) must be burned to provide...

He gas is confined to a piston and cylinder with a mechanical stop that prevents the cylinder from expanding. The temperature of the gas is 298 K, the volume of gas in the cylinder is 1.20 L and its pressure is 2.15 bar. The ideal gas EOS is very accurate for He under these conditions. The mechanical stop is a nut on a threaded rod that can be turned, slowly allowing the gas in the cylinder to expand. This process...

A 10 cm -diameter cylinder contains argon gas at 10 atm pressure and a temperature of 60∘C . A piston can slide in and out of the cylinder. The cylinder's initial length is 23 cm . 2700 J of heat are transferred to the gas, causing the gas to expand at constant pressure. Part A What is the final temperature of the cylinder? Part B What is the final length of the cylinder?

The gas inside a cylinder expands against a constant external pressure of 0.906 atm from a volume of 3.61 L to a volume of 14.50 L. In doing so, it turns a paddle immersed in 0.926 L of liquid octane (C8H18). Calculate the temperature rise of the liquid, assuming no loss of heat to the surroundings or frictional losses in the mechanism. Take the density of liquid C8H18 to be 0.703 g cm-3 and its specific heat to be 2.22...
