How much energy is required to increase the temperature of 14.2 grams of solid copper from 22.9 to 36.3 degrees celsius?
a) 69.5 J
b) 120.1 J
c) 50.3 J
d) 84.7 J

Answer :

To find the energy required to heat 14.2 grams of copper from 22.9 to 36.3 extdegree C, use the specific heat capacity formula with the specific heat of copper, which is 0.390 J/g extdegree C.

To calculate the energy required to increase the temperature of 14.2 grams of solid copper from 22.9 to 36.3 degrees Celsius, we can use the specific heat capacity formula:

Q = mc *Triangle

where Q is the heat energy, m is the mass, c is the specific heat capacity, and riangle T is the change in temperature. From the supplied information, copper has a specific heat capacity of 0.390 J/g extdegree C. The change in temperature ( riangle T) is 36.3 extdegree C - 22.9 extdegree C = 13.4 extdegree C. Plugging the values into the formula, we get:

Q = (14.2 g)(0.390 J/g extdegree C)(13.4 extdegree C)

Q = 74.8128 J
