The heat from the Bunsen burner transfers to the water and the pot, then the heat from the pot transfers to the person’s hand.
The flashlight's beam will all be refracted towards a central axis. But, this is still dependent on the type of lens that is used for the said activity. The speed of light will vary depending whether the lens is a concave or a convex lens. The exit point of the light will always head towards the central axis.
The rules of writing name is that they start with a big letter LIKE this and ends like this
Answer:

Explanation:
Since we are given the mass, specific heat, and temperature, we should use the following formula for heat energy.

The mass of the aluminum is 26.3 grams. Its specific heat is 0.930 Joules per gram degree Celsius. We need to find the change in temperature.
- The change in temperature is the difference between the initial temperature to the final temperature.
- The temperature changes <em>from</em> 23.0°C <em>to</em> 67.0°C, so the initial is 23 degrees and the final is 67 degrees.
- ΔT= final temperature - initial temperature
- ΔT= 67°C - 23°C
- ΔT= 44°C
Now we know all the values.
- m= 26.3 g
- c= 0.930 J/g °C
- ΔT= 44°C
Substitute the values into the formula.

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

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

<u>1076.196 Joules</u> of heat will be absorbed by the piece of aluminum.
