FINISH QUIZ
The c for aluminum is 0.900 J/g C. How much energy is needed to raise the temperature of a 952 g block of aluminum from
20.0 C to 37.0 C?
1 POINT

solidarity

Answer:

here's an example of one assignment it might help you

Explanation:

54827 J energy will required to increase the temperature from   22.8°C to 94.6°C

We have given mass of aluminium m = 900 J/gram°C

Mass of the aluminium m = 850 gram

The temperature of the aluminium is increases from 22.8°C to 94.6°C

So increase in temperature \Delta TΔT = 94.6 - 22.8 = 71.8°C

We have to fond the energy required to raise the temperature

We know that energy is given by Q=mc\Delta TQ=mcΔT , here m is mass, c is specific heat and \Delta TΔT is increase in temperature

So energy Q=850\times 0.9\times 71.8=54827JQ=850×0.9×71.8=54827J

So 54827 J energy will required to increase the temperature from   22.8°C to 94.6°C
