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

To find the value of Q, we need to use the equation Q = mcΔt, where Q is the heat energy transferred, m is the mass of the object, c is the specific heat capacity, and Δt is the change in temperature.

Given: m = 200 kg t1 = 40 °C (Initial temperature) t2 = 1740 °C (Final temperature) c = 140 J/(kg*°C)

First, we need to calculate the change in temperature (Δt): Δt = t2 - t1 Δt = 1740 °C - 40 °C Δt = 1700 °C

Now, we can calculate Q using the equation Q = mcΔt: Q = (200 kg)(140 J/(kg*°C))(1700 °C) Q = 4,760,000 J

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