Question

Q1 =4200Дж/кг * ⁰с * 0,06 кг* (60 ⁰с - 21 ⁰с) =

Answer 1

Q1 = 589 680Дж (589,68 кДж≈590кДж (заокругленого) )

Answer 2

To calculate the value of Q1 using the given equation, we can substitute the values and perform the calculations:

Q1 = 4200 J/kg·°C * 0.06 kg * (60 °C - 21 °C)

First, we need to calculate the temperature difference:

60 °C - 21 °C = 39 °C

Now we can substitute this value back into the equation:

Q1 = 4200 J/kg·°C * 0.06 kg * 39 °C

Q1 = 9828 J

Therefore, the value of Q1 is 9828 Joules.
