A substance has a specific heat of 0.870 J/g°C. It requires 2,000.0 joules to increase the temperature of 10.0 grams of the substance from its original temperature to its final temperature.
By how many degrees did the substance increase?
87.0°C
174°C
230°C
1,740°C

Respuesta :

Answer: [tex]230^0C[/tex]

Explanation:

[tex]Q=m\times c\times \Delta T[/tex]

q = heat absorbed or released by a substance = 2000.0 J

m= Mass of substance = 10.0 g

c = specific heat of the substance = [tex]0.870 J/g^0C[/tex]

[tex]\Delta T=T_f-T_i[/tex] = Change in temperature

Putting in the values we get:

[tex]2000.0J=10.0g\times 0.870J/g^0C\times \Delta T[/tex]

[tex]\Delta T=230^0C[/tex]

Thus the temperature changed by [tex]230^0C[/tex].
