M = 200 t1 = 40 t2 - 1740 c = 140 дж/кг*⁰с Q - ?

To find the value of Q, we can use the formula:

Q = m * c * ΔT

Where: Q = heat energy m = mass (in kg) c = specific heat capacity (in J/kg*⁰C) ΔT = change in temperature (in ⁰C)

Given: m = 200 kg c = 140 J/kg*⁰C ΔT = t2 - t1

ΔT = 1740 - 40 = 1700 ⁰C

Substituting the values into the formula:

Q = 200 kg * 140 J/kg*⁰C * 1700 ⁰C

Q = 4,760,000 J

Therefore, the value of Q is 4,760,000 J.
