A fixed amount of ideal gas is held in a sealed container. The initial volume, pressure, and temperature are [recall that 1L = 10−3 m3, and 1atm = 101,300Pa] V = 40 L P = 2.5 atm T = 400 K. (a) Compute the new temperature if the pressure is reduced to P = 1.0atm while the volume is held constant. (b) Compute the new volume if the temperature increases to 600K while the pressure is reduced to 2.0atm. (c)...

A sample containing 8.00 g of O2 gas has a volume of 35.0 L at constant pressure and temperature. (Help Please ASAP) i. A sample containing 8.00 g of O2 gas has a volume of 35.0 L at constant pressure and temperature. What is the new volume, in liters, after 0.550 mole of O2 gas is added to the initial sample 8.00 g of O2? ii. A sample containing 8.00 g of O2 gas has a volume of 35.0 L...
The amount of heat needed to raise the temperature of 1 mole of a substance by...
The amount of heat needed to raise the temperature of 1 mole of a substance by one Celsius degree (or, equivalently, one kelvin) is called the molar heat capacity of the system, denoted by the letter C. If a small amount of heat dQ is put into n moles of a substance, and the resulting change in temperature for the system is dT, then C=1ndQdT. This is the definition of molar heat capacity--the amount of heat Q added per infinitesimal...

gas is directly proportional to the Kelvin temperature of the gas, if the volume and amount of gas remain constant B) The total pressure exerted by a mixture of gases in a container is the sum of the partial pressures that each gas would exert alone. C) The volume of a gas is directly proportional to the number of moles of the gas, if the pressure and temperature remain constant D) The volume of a gas is directly proportional to...

infrin A box of mass M = 2 kg is held to two opposite walls by two springs each of spring constant k=115 N/m. For simplicity, you may assume that when the box is halfway between the two walls, both springs are relaxed. With what frequency does it oscillate? s-1 Help Reset Enter fo = 1.706 1.706 OK Suppose now we change the problem so that the left and right springs have spring constants kı = 161 and...
