Calculate the total heat energy in Joules needed to convert 20g of substance X from -10 degrees C to 70 degrees C. This is a heating curve question, I know I need to use the temperature change equation W=mCdeltaT. But I'm not sure what to do, can someone show me step by step how to solve this? Thank you!
