We heated 500g of graphite from 30 ° C to 35 ° C How much heat did we transfer to the graphite?
| December 16, 2020 | education
The amount of heat (Q) is found by the formula:
Q = cm (t2-t1);
To find, translate 500 grams into kilograms and substitute all the values
500 g = 0.5 kg
c (graphite) = 840 J / (kg * C)
Q = 840 * 0.5 * 5 = 2100 (J)
Answer: Q = 2100 (J) = 2.1 (KJ)
