Part A An underground tank with a capacity of 1850 L (1.85 m³ ) is completely filled with ethanol that has an initial temperature of 19.3°C. After the ethanol has cooled off to the temperature of the tank and ground, which is 10.1° C, how much air space will there be above the ethanol in the tank?

A 689.00g block of gold ( cgold=129 J kg°C ) initially at 15.00°C is placed in thermal contact with an unknown mass of aluminum ( calum=900 J kg°C ) initially at 90.00°C . If they equilibrate at a final temperature of 68.00°C , what is the mass of the aluminum? g What assumption do we make when solving calorimetry problems like this? We can only have two substances in thermal contact. The substances are in a closed, isolated container that does not allow any energy to enter or leave the system. The two substances must have different specific heats. Some of the energy transferred from one substance is lost to its surroundings and does not go to the other substance.
For a planet to have an atmosphere, gravity must be sufficient to keep the gas from escaping The escape speed a particle needs to escape the earth's gravitational attraction is 1.1 x 10 m/s. The motion of projectiles never depends on mass, so this escape speed applies equally to rockets and to molecules in the earth's upper atmosphere.
