A moonshiner makes the error of filling a glass jar to the brim and capping it tightly. The moonshine expands more than the glass when it warms up, in such a way that the volume increases by 0.5% (that is, ΔV/V0 = 5 10-3) relative to the space available.
Part 1: Bullet A 52 g bullet is fired from a height of 458 m. The initial speed of the bullet is 140 m/s. The bullet eventually comes to rest in a bucket containing 2.9 kg of olive oil that is at ground level. As a result of bringing the bullet to a stop (any change in PE while in the olive oil is negligible), how much does the temperature of the olive oil increase (express the answer in K)? Also determine how fast the bullet is going at impact. Ignore air drag and assume that all of the thermal energy generated goes into heating the olive oil. Impact speed = AT= Part 2: Nail A 0.52 kg hammer strikes a 28 g copper nail into wood board. The nail is horizontally aligned and at the moment of impact with the nail, the hammer had a speed of 8.9 m/s. Assume both the hammer and the nail come to a stop and that all of the thermal energy generated goes into heating the nail. Determine how much the temperature of the nail will increase after one hit and how many hits it will take to increase its…
A 0.0545 kg chunk of an unknown metal that has been in boiling water for several minutes is quickly dropped into an insulating Styrofoam beaker that contains 0.462 kg of water at room temperature (20.0° C). After waiting for a few minutes, you observe that the water's temperature has reached a constant value of 22.0° C. Part A Assuming that the Styrofoam absorbs a negligibly small amount of heat and that no heat was lost to the surroundings, what is the specific heat of the metal? Express your answer in joules per kilogram-kelvin to three significant figures. ΑΣφ J/(kg · K) C = Submit Request Answer Part B Use the table below to identify the metal.

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.
