How much heat energy is needed to raise the temperature of 2.06 kg of this oil from 23 °C to 191 °C?
-
You want to heat 2.06 kg of this oil from 23 °C to 191 °C, so you basically just use your specific heat capacity of 1.75 J/(g·°C) into your calculation
2.06kg = 2060g
change in temperature is 191-23=168 C
the units cancel out
2060g x 1.75 J/(g·°C) x (168C) = 605,640 J or 605.64 KJ
2.06kg = 2060g
change in temperature is 191-23=168 C
the units cancel out
2060g x 1.75 J/(g·°C) x (168C) = 605,640 J or 605.64 KJ
