It’s B. Substitution hope this helps
Answer:
think what you mean is that metal FEELS colder than wood if they're both at room temperature. That's because metal conducts heat much better than wood does. Since your hand is hotter than room temperature, both the metal and the wood conduct heat away from it.
The final temperature after absorbing the energy of 990 J is 25.014 °C.
Explanation:
The specific heat capacity formula can be used to solve the given problem.
So here the heat absorbed or the Q value is given as 990 J. Then the mass of the sample of water m is given as 59 g. The initial temperature is said to be 21 °C and the final temperature has to be determined.
The specific heat capacity is given as 4.18 J/g°C.
Then,
So, the difference in temperature or the change in temperature has to be determined first.
So, the change in temperature = ΔT = T₂-T₁ = 4.014 °C
T₂-21 = 4.014
T₂ = 4.014+21 = 25.014 °C.
So, the final temperature after absorbing the energy of 990 J is 25.014 °C.
Because of the wind and the cold from ur breath
