A bomb calorimeter, or constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy content of foods. Since the "bomb" itself can absorb energy, a separate experiment is needed to determine the heat capacity of the calorimeter. This is known as calibrating the calorimeter. In the laboratory a student burns a 0.749-g sample of acetylsalicylic acid (C9H8O4) in a bomb calorimeter containing 1030. g of water. The temperature increases from 24.10 °C to 27.20 °C. The heat capacity of water is 4.184 J g-1°C-1. The molar heat of combustion is −3869 kJ per mole of acetylsalicylic acid. C9H8O4(s) + 9 O2(g) 9 CO2(g) + 4 H2O(l) + Energy Calculate the heat capacity of the calorimeter. heat capacity of calorimeter = J/°C

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
