B

<u>Clapping hands</u>  is a best scenario that describes a transfer of mechanical energy to heat and sound energy

Explanation:

The action of clapping your hands is mechanical hence has mechanical energy. When you clap your hands you make a sound because you cause vibrations in the air around the clapping hands. This is a transformation of the mechanical energy to sound energy. You realize that clapping your hands causes your hands to get warmer. Some of the mechanical energy was also transformed into heat energy.

An iron bar of mass 841 g cools from 84°C to 7°C. Calculate the heat released (in kilojoules) by the metal.
Oduvanchick [21]

Answer:

28.75211 kj

Explanation:

Given data:

Mass of iron bar = 841 g

Initial temperature = 84°C

Final temperature = 7°C

Heat released = ?

Solution:

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

specific heat capacity of iron is 0.444 j/g.°C

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = 7°C - 84°C

ΔT = -77°C

By putting values,

Q = 841 g × 0.444 j/g.°C × -77°C

Q = 28752.11 j

In Kj:

28752.11 j × 1 kJ / 1000 J

28.75211 kj
