Question

What should be measured to calculate the average rate at which the water in a cup cools?

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

Answer 1

Im thinking its D

Answer 2

yes

Answer 3

average rate of cooling = \[\frac{ T2-T1 }{ t2-t1 }\]

where t= time and T= temp

Answer 4

Ok

Answer 5

Thank you!

Answer 6

Why would you need to measure, the mass, weight, or volume if you want to measure the rate of temperature loss (cooling)

Answer 7

Yeah.. I was just checking my answer
