WebShort answer: No. Many would be tempted to say that high temperature = lots of energy, and low temperature = not much energy. This would mean energy flows from objects which have lots of energy to objects which have less energy. This makes some sense. When you heat something up, energy is added to it. WebThe symbol of the heat of fusion is ΔHf. The formula of the heat of fusion is ΔHf = q/m or q = m·ΔHf (both are the same, anyhow). Note: the temperature does not really change when matter changes its state, so the temperature is not in the equation or required for the calculation. The melting of helium is the only exception. WebTemperature sensors convert thermal energy into electrical signals. For this to happen, thermal energy is first transferred from the sensed object to the sensor, which can occur through direct contact or radiation. In either case, heat transfer is required. After the transfer of energy, there are two ways in which the sensor can convert the ... craig cd jukebox
