Activity 7Number 1.2 only Activity #7PROBLEM SOLVING ACTIVITY: IDEAL GAS LAW1. Solving ldeal Gas Law Problems Directions: Use the ideal gas law, "PV-nRT", and the universal gas constant R= 0.0821 L*atm to solve the following problems: K*mol If pressure is needed in kPa then convert bymultiplying by 101.3kPa / 1atm to get R =8.31 kPa*L/ (K*mole). Show your answers legibly, concisely, andcompletely. Use separate sheet of paper.1.1.If I have 4 moles of a gas at a pressure of 5.6 atm and a volume of 12 liters, what is thetemperature?If I have an unknown quantity of gas at a pressure of 1.2 atm, a volume of 31 liters, and atemperature of 87 0 C, how many moles of gas do I have?If I have 7.7 moles of gas at a pressure of 0.09 atm and at a temperature of 56 0 C, what is the1.2.1.3.volume of the container that the gas is in?1.4.If I contain 3 moles of gas in a container with a volume of 60 liters and at a temperature of 400 K,what is the pressure inside the container?2. Directions: Solve the following heat engine work done related problems. 1. During a cyclic process, a heatengine absorbs 350 J of heat from a hot reservoir, does work and ejects an amount of heat 100 J into thesurroundings (cold reservoir). Calculate the efficiency of the heat engine? 2. A steam engine boiler ismaintained at 250°C and water is converted into steam. This steam is used to do work and heat is ejected tothe surrounding air at temperature 300K. Calculate the maximum efficiency it can have?
