Answer:
40.7 kJ
Step-by-step explanation:
The formula for the heat, q, needed to evaporate a liquid is
q = mΔHvap
<em>Data: </em>
m = 180 g
ΔHvap = 2260 J/g
<em>Calculation:
</em>
q = 180 g × 2260 /1
q = 40 700 J = 40.7 kJ
The answer is false methane is emitted from coal
no...the atoms will not behave the same
as when temperature is increased, the atoms vibration and kinetic energy will also be increased....they come in excited state...
where as when temperature is reduced ,atoms kinetic energy slows down....
Answer:
Charging a chemical battery is a simple example of converting electricital energy to chemical energy.
