The hotness of an object is determined by its temperature, true or false?
Answer- True
Explanation:- The terms ‘hot’ and ‘cold’ are used in our daily life and are related to each other. Temperature is the quantitative measure to illustrate the hotness of an object, and a thermometer is a measuring apparatus used to compute temperature.
- The hotter the body, the higher its temperature is. Firstly objects that are at different temperatures, in the beginning, come in contact with each other and then slowly come to a common temperature due to the movement of heat from a body that has a higher temperature at the beginning to the body which has a lower initial temperature at the beginning. This is true of solids, liquids, and gases.
- The degree of hotness is given the name temperature and its value changes in a continuous manner. A ‘hotter’ body entails a higher temperature whereas a ‘cooler’ body entails a lower temperature.
- Galileo Galilei was the one who successfully made one of the earliest attempts to construct a way to measure the degree of hotness in the form of a device known as a gas thermoscope, which can be said to be the predecessor of the thermometer. A thermoscope is a device that is based on the expansion of gas due to variation in the degree of hotness.
- Thermometers are one of the most used devices across the globe. We come across various thermometers in our daily life (in laboratories, clinics, etc). We often go through the various reports relating to temperatures, such as a weather report, the body temperature of a patient, or the temperature of a chemical solution in the lab.
- These temperatures are variously reported as “so many degrees Celsius”, or “so many degrees Fahrenheit”. We use the Celsius scale for all our work, and treat the number indicated by the alcohol or mercury column as the degree of hotness, or temperature.
