Arte-miy333 [17]

We have that heat flow out of the copper sample  is mathematically given as

Q=8.86809J

<h3> Heat flow</h3>

Question Parameters

  • A temperature of a 0.349 kg sample of copper
  • decreases from 87.0 °C to 21.0 °C.

Endothermic Reaction

It is common knowledge that an endothermic reaction is one where the system absorbs heat energy from the <em>environs</em>.

Exothermic Reaction

An exothermic reaction is one where the system releases heat energy to the <em>environs</em>.

Generally the equation for Heat   is mathematically given as

Q=mCdt\\\\Therefore\\\\Q=0.349*0.385*(87-21)

Q=8.86809J
