It took 73.2 J of heat to raise the temperature of 10.0g of a substance 8.58°C. What is the
specific heat of the substance?

Respuesta :

Answer:

[tex] \boxed{\sf Specific \ heat \ of \ the \ substance \ (c) = 0.85 \: J/g \degree C } [/tex]

Given:

Mass (m) = 10.0 g

Rise in temperature (∆T) = 8.58°C

Energy required (Q) = 73.2 J

To Find:

Specific heat of the substance (c)

Explanation:

Specific heat (c) of a substance is the energy required to raise the temperature of one gram of the substance by one degree Celsius.

Formula of specific heat is given as:

[tex] \boxed{ \bold{c = \frac{Q}{m\Delta T}}}[/tex]

By substituting value of Q, m & ∆T in the formula we get:

[tex] \sf \implies c = \frac{73.2}{10 \times 8.58} \\ \\ \sf \implies c = \frac{73.2}{85.8} \\ \\ \sf \implies c = 0.85 \: J/g \degree C [/tex]
