Is heat index the same as temperature
Web1 day ago · Overnight lows are also staying warm, which doesn’t allow for much recovery from the heat. More than 75 record-high minimum temperatures could be set by Saturday morning. WebTemperature is a measure of the average kinetic energy of the atoms or molecules in the system. The zeroth law of thermodynamics says that no heat is transferred between two objects in thermal equilibrium; therefore, they are the same temperature. We can calculate the heat released or absorbed using the specific heat capacity \text C C
