You'll need the specific heat capacity of aluminium to solve this question.
H=(0.005)(37-22)(specific heat capacity of aluminium)

Answer: 67.65 Joules

Explanation:

$Q= m\times c\times \Delta T$

Q= heat gained

m= mass of the substance = 5.0 g

c = heat capacity of aluminium = 0.902 J/g ° C

$\Delta T={\text{Change in temperature}}=(37-22)^oC=15^0C$

$Q=5.0g\times 0.902J/g^oC\times 15^oC$

Q= 67.65 Joules

Thus heat gained by 5.0 g of aluminum is = 67.65 Joules

Compare the costs of using renewable resources to the costs of using nonrenewable resources.

Vitek1552 [10]

Answer:

Sample response:

The costs of using both renewable and nonrenewable resources depend on the extent of the use. If renewable resources are managed wisely, the use of the resource will not exceed the rate at which it is replenished. In this instance the cost of using renewable resources can be minimized, if not entirely eliminated. The cost of using nonrenewable resources is harder to minimize because nonrenewable resources cannot be replenished at the rate at which they are used. The environmental impact of using nonrenewable resources such as fossil fuels is greater than just the loss of the resource itself. Other impacts such as acid rain, global warming, and atmospheric pollution can result from the use of nonrenewable resources.
