Does anyone know how to do this? :uhh: I've tried to figure it out but it aint working =/ its for a test i gotta turn in now. argh. The specific heat capacity of water is high, 4.184 J/gºC. The presence of impurities in a sample of water lowers its specific heat capacity. What is the specific heat capacity of the sample if 100 grams of it now requires 200 Joules of heat for a 1.8ºC temperature increase? What are the effects of the low specific heat capacity of the sample of water? Its okay if anything, i just need to pass this test, anything would help about now. Thank you guys very much.
