how much energy is required to heat 40.0 grams of water from 25°C to 75°C? The specific heat capacity of water is 4.184 J/g.

Q = 8368J

Explanation:

Mass (m) = 40g

Initial temperature (T1) = 25°C

Final temperature (T2) = 75°C

Specific heat capacity (c) = 4.184J/g°C

Heat energy (Q) = ?

Q = Mc∇T

Q = Mc * (T2 - T1)

Q = 40 * 4.184 * (75 - 25)

Q = 167.36 * 50

Q = 8368J

The heat energy required to raise the temperature from 25°C to 75°C is 8368J
