How much energy does it take to raise the temperature of 80g of aluminium 15 degree Celsius

Explanation:

We are asked to calculate the energy needed to raise the temperature of 80 grams of aluminum by 15 degrees Celsius.

We are given the mass and change in temperature, so we will use the following formula:

The mass is 80 grams, the change in temperature is 15 degrees Celsius, and aluminum's specific heat capacity is 0.9 Joules per gram degree Celsius.

Substitute the values into the formula.

Multiply the first two numbers together. The units of grams will cancel out.

Multiply again. This time, the units of degrees Celsius cancel.

Raising the temperature of 80 grams of aluminum by 15 degrees Celsius requires 1080 Joules of energy.

it's filtration, but this is an assumption so my apologies if i got this

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
