Question

Q=10000000дж q=10000000 дж/ кг Найти m

Answer 1

Решение:
m=Q/q=1000000/1000000=1 кг

Answer 2

The equation that relates energy (Q), mass (m), and specific heat (q) is:

Q = m * q

Where: Q = energy in Joules (J) m = mass in kilograms (kg) q = specific heat in Joules per kilogram per degree Celsius (J/kg°C)

Assuming that the specific heat is given in terms of temperature change in Celsius, we can use the specific heat of water (4.18 J/g°C) as an estimate for q.

Converting Q to Joules per kilogram, we have:

Q = 10000000 J/kg

Substituting this into the equation and using the estimate for q, we get:

10000000 J/kg = m * 4180 J/kg°C

Simplifying, we get:

m = Q / (q * ΔT)

Where ΔT is the temperature change. If ΔT is not given, we cannot solve for m using this equation.

However, if we assume that ΔT is 1°C, we can solve for m as follows:

m = 10000000 J/kg / (4180 J/kg°C * 1°C) ≈ 2388 kg

Therefore, if the temperature change is 1°C, the mass is approximately 2388 kg.
