What is the specific heat of an unknown substance if 100.0 g of it at 200.0 °C reaches an equilibrium temperature of 27.1 °C when it comes in contact with a calorimeter of water. The water weighs 75. g and had an initial temperature of 20.00 °C? (Specific heat of water is 4.18 J/g°C)
0.111 J/g°C
1.29 J/g°C
0.129 J/g°C
22225.85 J
For a skillet, used for cooking, do you want a high or low specific heat
High, so that it will need more energy to heat up
Low, so that it will change temperature quickly
