The joule (J) is the unit of measure for energy used in the International System of Units (SI), and the one accepted in scientific circles. The unit is used in all equations and calculations involving energy. Following SI conventions, joules are abbreviated with a capital J because the term...
Specific Heat Capacity of Water at normal temperature and pressure is roughly4.2 J/goC. This means that 1 gram of water requires 4.2 joules of energy to raise 1 degree Celsius. Water has a high specific heat capacity. The actual value of water’s specific heat capacity is4182 J/kg °C. ...
