Okay whats the question though?
Answer:when the heat is absorbed by a system, the reaction is endothermic
Explanation:
Answer:
Explanation:
We know that heat relates to mass, specific heat and variation of temperature experimented because of this heat through the equation . The heat released by the unknown material is absorbed by water, so we have , and we can write:
Since thermal equilibrium is reached we know that , where we have added to convert the temperature from Celsius to Kelvin, as <em>we must do</em>. Since we want the specific heat of the unknown material, we do:
Which for our values is:
C. Falling unstable air forms a cold airmass
