A 100 gram piece of ice is placed in an insulated calorimeter of negligible heat capacity containing 100 grams of water at 373K.

a. What is the final temperature of the water once thermal equilibrium is established?

b. Find the entropy change of the universe for this process.

What’s #16 asking and how do i solve it?

Your science teacher brings in a speaker to talk to your class about climate change. during the session, students ask a few questions. which questions are related to the current evidence on climate change

An object with initial temperature 130 ∘ f is submerged in large tank of water whose temperature is 50 ∘ f . find a formula for f ( t ) , the temperature of the object after t minutes, if the cooling constant is k = − 0.2 . remember newton's law of cooling (the rate of change of temperature with respect to time is equal to k times the difference between the temperature of the object and the surrounding temperature) ! : )
