An 80.0-g piece of copper, initially at 295°c, is dropped into 250 g of water contained in a 300-g aluminum calorimeter; the water and calorimeter are initially at 10.0°c.

what is the final temperature of the system? (specific heats of copper and aluminum are 0.092 0 and 0.215 cal/g⋅°c, respectively. cw = 1.00 cal/g°c)
a. 12.8°c
b. 16.5°c
c. 28.4°c
d. 32.1°c

b. 16.5°C

Explanation:

= mass of piece of copper = 80 g

= specific heat of piece of copper = 0.0920 cal/g°C

= Initial temperature of piece of copper = 295 °C

= mass of water = 250 g

= specific heat of water = 1 cal/g°C

= Initial temperature of piece of copper = 10 °C

= mass of calorimeter  = 300

= specific heat of calorimeter = 0.215 cal/g°C

= Initial temperature of calorimeter = 10 °C

= Final equilibrium temperature

Using conservation of heat

Heat lost by piece of copper = heat gained by water + heat gained by calorimeter

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.

report!

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
