4. What is normal body temperature?
TIME AND TEMPERATURE:
Time is a continuous sequence of events and existence in irreversible succession from past to present into the future.
In the laboratory stopwatch or stop-clock are used to measure time. Accurate stopwatches can measure upto 0.01s. It is measured in its SI unit which is second. Other units are minute, hour, day, millisecond, micro and nanosecond, etc.
Temperature is a physical quantity used to measure the hotness and coldness of a substance. The temperature of a gas or a liquid can be measured using a thermometer. Commonly degree Celsius (°C) is used but in the laboratory, Kelvin is used. Alcohol in glass and mercury in glass thermometers are used in the laboratory. To reduce the risk of mercury poisoning electronic thermometers are used. Thermal sensors and probs are used to record the temperature of a liquid over a period of time. Such data is then fed to a computer for the graph of temperature against time. Data loggers are used to analyze and store these types of experimental data.

What is normal body temperature?
The normal body temperature of a human is 37 degrees Celsius (°C). If the temperature increase or decreases from 37 degrees Celsius (°C) the enzymes starts to denature.
