T = final temperature of the block
T₀ = initial temperature of the block = 23.4 °C
Q = energy lost from the wooden block = - 759 J
c = specific heat capacity of wood = 1.716 J/(g °C)
m = mass of the wooden block = 27.2 g
Heat lost from the block is given as
Q = m c (T - T₀)
inserting the values
- 759 = (27.2) (1.716) (T - 23.4)
T = 7.1 °C
A. To determine how to break down minerals
A hydrate is a substance that contains water or its constituent elements. When this substance is heated, water is evaporated leaving an unhydrate. From this sample, the amount of water present would be equal to 2.73 g. Hope this answers the question. Have a nice day.
