Lend has a specific heat of 128 J/kg°C. A lead bullet is moving at 650 m/s. If the bullet is suddenly stopped so that all of its kinetic energy is converted into heat, determine the temperature that the lead bullet reached before it was stopped. Take the initial temperature of the bullet to be 30 °C.

To determine the specific heat of an object, a student heats it to 100 ∘C in boiling water. She then places the 87.2 g object in a 173 galuminum calorimeter containing 136 g of water. The aluminum and water are initially at a temperature of 19.8 ∘, and are thermally insulated from their surroundings. If the final temperature is 23.4 ∘, what is the specific heat of the object? Referring to the table, identify the material in the object. Substance...

Specific Heat (more precise) The heat capacity of an object indicates how much energy that object can absorb for a given increase in that object's temparature. In a system in which two objects of different temperatures come into contact with one another, the warmer object will cool and the cooler object will warm up until the system is at a single equilibrium temperature. Note the difference between the terms molar heat capacity, which has units of J/mol- Degree C, and...
