Two objects A and B are of similar surface nature. The area of the emitting surface of B is as twice as of that of A. If you know that object A is at an absolute temperature T, and that object B is at half of this temperature calculate the ratio of H of object A to H of object B. H is the heat current in radiation of an object. Show all the work needed to derive your answer.

This problem will require you to upload images of your work for credit. Label this "Problem C." I have a bowl of warm water (2 kg at 40° C) and I plop 0.5 kg of dry ice into it to produce that cool Halloween fog! The dry ice immediantly sucks heat out of the water and sublimates into a gas. Once all the CO, has left.. will some of the water be frozen? Justify, in your work, the answer you choose. and the latent heat of sublimaion of dry ice is 199.000 kg (Note: The specific heat of liquid water is 4182 kg °C Yes, my math shows that the final temperature of the water wants to go below 0 degrees. Therefore, some will freeze. O No, my math shows the final temperature of the water will be greater than 0 degrees.

Please explain and solve clearly. Write all answers to 3 significant figures and include proper units. Properties of Gold: Specific Heat: 126 J/(kg.K) Linear Coefficient of Thermal Expansion 1.40x10^-5 (C^-1)

For the diagram shown below, if an ideal gas transition from point A to point D, then: the Temperature of the gas sample will____? the Pressure of the gas sample will______?

Can you please answer this question and all of the sub parts and show all of the steps to the solution
