We can directly measure the temperature of a cup of coffee

We can directly measure the temperature of a cup of coffee but we cannot directly measure its enthalpy Which statement explains why enthalpy cannot be measured directly Choose the correct answer Enthalpy is a measure of heat that is lost and this heat cannot be measured during a reaction while particles are moving Temperature has an absolute zero but enthalpy is a measure of energy transferred as heat and because particles always have energy enthalpy cannot be zero so we can only measure the change in enthalpy Temperature is measured by its effect on an external object with a thermometer while enthalpy never O affects substances outside the system so there is no way to directly measure the energy with a tool such as a thermometer Temperature measures the total kinetic energy of the particles in the coffee but enthalpy measures the average kinetic energy which cannot be found directly and must be calculated
