Radiation by means of physics related terms is defined as the emission or transmission of energy in the form of waves or particles through a. The general defined term of convection is the heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it (Georgia State University). In that case it can be determined by measuring the temperature change T for the contents of the calorimeter and using their specific heat - the heat required to raise the temperature of 1 gram of the substance by 1C. The average specific heat of the unknown metal was 0.197C and was determined using a calorimeter. We then measured out 50.0mL of heated deionized water into a graduated cylinder and placed a temperature probe in the graduated cylinder. Set up 600 mL beaker and add 400 mL of dis"lled water inside and place it on a hot For example, the unknown metal may not have set in the water bath long enough to reach the same temperature as the water causing inaccurate results when reading temperature.
