A 295-g aluminum engine part at an initial temperature of 13.00°C absorbs 75.0 kJ of heat. What is the final temperature of the part (c of Al = 0.900 J/g·K)?

Respuesta :

A 295-g aluminum engine part at an initial temperature of 13.00°C absorbs 75.0 kJ of heat. The final temperature of the part is 295.5 °C.

The heat required, q, is equal to the Specific Heat Capacity, C, times the amount of the substance times the temperature change, that is (T final - T initial) in degrees C or K.

(Remember, a difference in temperature on the C scale is equivalent to that same amount on the Kelvin scale.)

So we have, q = C x m x (T final - T initial).

Let T final = T

Now, (T final - T initial) = (T) - (13 )

So,

q = C m  (T final - T initial)

 75kJ = (0.900 J/gK)  (295g) [(T) - (13 ) ]

1kJ = 1000 J

75000 = (0.900 J/gK)  (295g) [(T) - (13 ) ]

[(T) - (13 ) ] = 75000/ (0.900 x 295)

[(T) - (13 ) ] = 282.5

T = 282.5 +13

T = 295.5 °C
