You make a cup of hot coffee and pour it into an insulated container that already has ice in it. Assume that the insulated container itself has a very small heat capacity so that any energy transferred from it or to it is negligible and can be ignored. What energy systems are changing. starting from when you pour the coffee into the insulated container to when the ice is completely melted and the mixture has a uniform temperature? Ethermal, coffee,...

A hot block of iron is placed on top of a block of ice at Tiwater--60° C in an insulating container so no heat can be transferred into or out of the container. When you open the container later the ice has completely melted. For the physical system of the iron and water, what energy systems changed from the time the iron is placed insided to the time the container is opened? Ebond, water O Ethermal, iron, Ethermal, water Ethermal...

Statistic Q1(a) Mr. Sweetheart likes sugar in his hot tea. He buys sugar packets from a local grocery store. Suppose the amount of sugar in a packet follows a normal distribution with mean 2.17 grams and standard deviation 0.08 grams. The amount of sugar in a package should be between 2.13 and 2.21 grams. Otherwise, a packet is considered to be defective. i. What is the probability that a randomly selected packet is defective? ii. Three sugar packets are chosen...
