Question

PLEASEE HELPP!! Kennedy has a part-time job at an ice skating rink selling hot cocoa. She decided to plot the number of hot cocoas she sold relative to the day's high temperature and then draw the line of best fit. Based on the line of best fit, how many hot cocoas would you predict Kennedy to sell if the day’s high temperature were 40 degree F

Answer 1

The solution involves calculating the heat transfer during the cooling and phase change of water and ice to determine the final equilibrium temperature of the system in a thermodynamics problem.

Step-by-step explanation:

The question is centered around the concept of thermodynamics in Physics, specifically the transfer of heat during phase changes and temperature changes. The scenario provided involves finding the final temperature of a system consisting of a small quantity of water at 20°C being poured onto a much larger mass of ice initially at -15°C. The calculation requires an understanding of the specific heat capacities of water and ice, as well as the latent heat of fusion for ice.

To solve for the final temperature, one would need to calculate the amount of heat lost by the water as it cools down and potentially freezes, and the heat gained by the ice as it warms up to 0°C and possibly undergoes a phase change into water.

Answer 2

Without knowing the actual data points and the equation of the line of best fit, it is impossible to accurately predict the number of hot cocoas Kennedy would sell if the day's high temperature were 40 degrees F. However, if you have the equation of the line of best fit, you can substitute 40 degrees F for the variable representing the day's high temperature and solve for the predicted number of hot cocoas sold.
