Identical amounts of thermal energy are added to each of three isolated, equal-mass samples A, B, and C of unknown substances. If their temperature changes are ordered as ΔTA > ΔTB > ΔTC, which sample has the largest specific heat?
Alright Dude, If that worked
for you... dont forget to give THUMBS UP.(that will work for
me!)
If I missed something feel free to leave a comment.
atleast before giving downvote.

1. Different amounts of thermal energy are added to each of three isolated samples, A, B, and C of lead. If the energy transfers are ordered as Qb>Qc>Qa and each sample undergoes the same temperature change, which samples has the largest mass? 2. A mouse is initially at rest on a horizontal turntable mounted on a frictionless vertical axle. As the mouse begins to walk clockwise around the perimeter which of the following statements must be true of the turntable?...
Objects A and B of equal mass are brought into close thermal contact with each other, but they are well isolated from their surroundings. Initially TA = 0°C and TB = 100°C. The specific heat of A is the same as the specific heat of B. The two objects will soon reach a common final temperature Tf. The final temperature is: a. Tf > 50°C. b. Tf < 50°C. c. Tf = 50°C.
Draw two lines to show how the temperature changes when equal amounts of thermal energy are added at the same rate to equal masses of water (sp ht 4.18 J/g °C) and ethanol (sp ht 2.44 J/g °C). Assume they both start at the same temperature (10 °C) and the ethanol ends up at 50 °C. Be sure to label your graphs to show which line corresponds to water and which to ethanol. - + + + + + +...
Two substances A and B, initially at different temperatures, are thermally isolated from their surroundings and allowed to come into thermal contact. The mass of substance A is twice the mass of substance B, but the specific heat capacity of substance B is four times the specific heat capacity of substance A. Which substance will undergo a larger change in temperature?
