Which is a measure of how hot or cold something is?

By measuring the temperature of a thing it can be determined whether it is hot or cold. Temperature of the thing can be measured by degree Centigrade or by degree Fahrenheit. This is the instrument that will exactly measure the temperature of the substance and whether it is hot or cold. If the substance has a higher temperature than our body temperature then it would automatically feel hot to us and if the temperature of the substance is lower than our body temperature, then it will definitely feel cold to us. This is our sense telling us whether the substance in question is hot or cold.
