How many joules of energy would it take to raise the temperature of 2.5 grams of magnesium metal from

25°C to 50°C

Report your answer with two significant digits, leave a space, and add the unit.

Q = 63.75J

Explanation:

Mass = 2.5g

Initial temperature (T1) = 25°C

Final temperature (T2) = 50°C

Specific heat capacity of Mg = 1.020J/g°C

Heat energy = ?

Heat Energy (Q) = mc∇T

Q = heat energy

M = mass of substance

C = specific heat capacity of substance

∇T = change in temperature = T2 - T1

Q = mc∇T

Q = mc (T2 - T1)

Q = 2.5 * 1.020 * (50 - 25)

Q = 2.55 * 25

Q = 63.75J

The heat energy required to raise magnesium metal from 25°C to 50°C is 63.75J
