A 0.4 kg aluminum part increases its temperature by 25°C. How much thermal energy is transferred to the part by heat? (specific heat of aluminum = 900 J/kg•°C) help its on a tes i need hel

Explanation:

Hello.

In this case, since the energy involved in a heating process is computed via:

Whereas m is the mass (0.4 kg), Cp is the specific heat (900 J/kg•°C) and ΔT the temperature rise (25 °C), the required heat turns out:

It means that 9000 J of energy is transferred to attain that temperature raise.

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.

i think? ?
