An insulated container contains two moles of an ideal gas at atmospheric pressure. Keeping the pressure constant, if the temperature of the gas is increased by 50 °C, then its volume increases by 400 cm3 and if the temperature is increased by 100 °C, then its volume increases by 600 cm³. Determine the initial volume and temperature of the gas. (Write the equation of ideal gas initially, after the temperature increase of 50 °C, and after increase of temperature by 100 °C. Combine these three equations to find the initial volume and temperature)

Aluminum rivets used in airplane construction are made slightly larger than the rivet holes and cooled by "dry ice" (solid CO₂) before being driven. Part A If the diameter of a hole is 4.500 mm, what should be the diameter of a rivet at 23.0°C, if its diameter is to equal that of the hole when the rivet is cooled to -78.0°C, the temperature of dry ice? Assume that the expansion coefficient of aluminum is 2.4 x 10-5 (°C)-¹ and remains constant. -1 Express your answer in milimeters to four significant figures. d = Submit 15. ΑΣΦ Request Answer ?
