Four samples of steel, lead, alcohol and glass all have the same mass and are all initially at 20 °C. After 100 calories of heat is added to each sample, the final temperatures are 38.2 °C for the steel, 85.6 °C for the lead, 23.4 °C for the alcohol, and 30 °C for the glass. Which of these four materials has the largest specific heat capacity? ( ) The steel ( ) The lead ( ) The alcohol ( ) The glass
