Answer:

1.8  J/ g ∘ C

Explanation:

A substance's specific heat tells you how much heat much either be added or removed from  1 g  of that substance in order to cause a  1 ∘ C  change in temperature.

The equation that establishes a relationship between specific heat, heat added or removed.

Answer:

2076.9 J/kg°C

Explanation:

The equation needed here is:

q=mC(T_f-T_i) , where q is the energy in Joules, m is the mass in kg, C is the heat capacity, T_f is the final temperature, and T_i is the initial temperature.

Here, we have q = 6.75*10^4 J, m = 1.30kg, T_f = 57, and T_i = 32. So:

6.75*10^4=1.30*C*(57-32)

Solving for C, we get:

C = 2076.9 J/kg°C

Hope this helps!

Makovka662 [10]
The rate of dissolution of a solid solute into the solution decreases when you stop stirring it. Generally, stirring increases the dissolution rate of a solid into a solution. An example is coffee with sugar, the sugar dissolves faster when stirred versus when left to dissolve on its own.
