. 8750 J of heat are applied to a piece of aluminum, causing a 66.0 oC increase in its temperature. The specific heat of aluminum is 0.9025 J/g oC. What is the mass of the aluminum?

Respuesta :

daienrode
146.8983 grams


EXPLANATION:


You can use the heat formula to find the mass

q=mc ΔT


The q stands for heat, which is given; 8750 Joules

The m stands for mass, which is our UNKNOWN

The c stands for specific heat, which is given; 0.9025 J/gC

The ΔT stabs for temperature change, which is
given; 66 C


So plug in all of your information into the formula.


8750= (m) (0.9025) (66)

8750= (m) (59.565)

146.8983= mass


Let me know if you have any questions.

The mass of aluminum supplied to given quantity of heat in order to increase its temperature is 146.9 g.

The given parameters;

  • heat applied to the aluminum, Q = 8750 J
  • increase in temperature of the aluminum Δt = 66 ⁰C
  • specific heat of aluminum, c = 0.9025 J/g⁰C

The mass of aluminum is calculated as follows;

Q = mcΔt

where;

  • m is the mass of the aluminum

[tex]m = \frac{Q}{c \Delta t} \\\\m = \frac{8750}{0.9025 \times 66} \\\\m = 146.9 \ g[/tex]

Thus, the mass of aluminum supplied to given quantity of heat in order to increase its temperature is 146.9 g.
