In a calorimeter with a heat capacity of 249 J / K one brings 400g water at 12.0 ° C. It leads vapor of boiling ethyl alcohol and will eventually test 32.2 g condensed alcohol. The final temperature is 28.0 ° C and the specific heat capacity of ethyl alcohol is 2.43 * 10 to the third J / kg. This to compute the specific evaporation heat of ethyl alcohol.
How much vapor of boiling water is needed to 500g of 10.0 ° C to 20.0 ° to heat?
In a calorimeter with a heat capacity of 105 J / K which contains 500 grams of water at 20.0 ° C, we charge 100 g of ice at 0.0 ° C. The final temperature of the system is 4.0 ° C. This to compute the specific heat of melting ice.
A block of iron of 5.00 kg of C is placed in a calorimeter with ice of 0.0 °. At a temperature of 100 ° C How can this ice melt?
