What should be measured to calculate the average rate at which the water in a cup cools? (4 points)
Change in mass of water and time in which the mass changes
Change in weight of water and time in which the weight changes
Change in volume of water and time in which the volume changes
Change in temperature of water and time in which the temperature changes
These kinda questions kinda confuse me. Im thinking its the first choice, but im not sure how to verify that. can anyone help me out..

They want you to find how what you'd measure to find the average rate.. Its obviously a change, in mass, weight, volume or temperature? What do you think?

Volume right?? because that's suppose to show for how much what is being filled if that makes sense

temperature at specific time intervals

campbell_st · Answer

the rate of cooling =  change in temp
