Explanation:

1) When we turn on the burner of the gas stove, we use mechanical energy. Mechanical energy is energy due to motion of an object.

Correct is option (c).

2)The ignition of the gas is a chemical energy. Chemical energy is is a energy which releases during the chemical reaction. Here gas id reaction with air to get ignite.

Correct is option (a).

3) The warming of the water in the pan by the help of burning gas is thermal energy. The thermal energy is an energy due to motion of the molecules or particles which can be transferred from one object to another in form of heat. Here the heat transferred to the pan by the burning of gas warms the water.

Correct is option (b).

How much heat does a 100. g sample of copper absorb when its temperature increases by 30.0°C? The specific heat of copper is 0.3
erica [24]

Answer:

\boxed {\boxed {\sf B. \ 1170 \ Joules }}

Explanation:

We are asked to find how much heat a sample of copper absorbs when the temperature is increased.

Since we know the mass, temperature increase, and specific heat capacity, we can use the following formula to calculate heat.

q= mc \Delta T

The mass of the copper sample is 100 grams, the temperature is changed or increased by 30.0 degrees Celsius, and the specific heat of copper is 0.39 Joules per gram degrees Celsius.

  • m= 100 g
  • c= 0.39 J/g °C
  • ΔT= 30.0 °C

Substitute the values into the formula.

q= (100 \ g )(0.39 \ J/g \textdegree C ) (30.0 \textdegree C )

Multiply the first two values. Note that the units of grams cancel.

q= 39 \ J/ \textdegree C (30.0 \textdegree C )

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

q= 1170 \ J

The copper sample absorbs <u>1170 Joules</u> of heat and <u>Choice B </u>is correct.
