Acopper block with a mass of 500 grams is cooled to 77k by being immersed in liquid nitrogen. the block is then placed in a styrofoam cup containing some water that is initially at +50.0°c. assume no heat is transferred to the cup or the surroundings. the specific heat of liquid water is 4186 j/(kg °c), of solid water is 2060 j/(kg °c), and of copper is 385 j/(kg °c). the latent heat of fusion of water is 3.35 x 10^5 j/kg. what is the mass of water in the cup, if the final temperature is -25.0°c? grams.
(a) calculate the maximum possible mass of water that could be in the cup. (g)(b) calculate the minimum possible mass of water that could be in the cup. (g)

An insurance company wants to know if the average speed at which men drive cars is higher than that of women drivers. the company took a random sample of 27 cars driven by men on a highway and found the mean speed to be 72 miles per hour with a standard deviation of 2.2 miles per hour. another sample of 18 cars driven by women on the same highway gave a mean speed of 68 miles per hour with a standard deviation of 2.5 miles per hour. assume that the speeds at which all men and all women drive cars on this highway are both approximately normally distributed with unknown and unequal population standard deviations.
