The increments on the thermometer are one-degree Celsius, therefore need to record the temperature to the nearest 0.1 Celsius (one decimal point place more precise than the increment).  Can you help me increments on the thermometer with the initial temperature of the water including the nearest 0.1 Celsius (one decimal point place more precise than the increment)? I'm not sure if it was the correct answer either 20.9 Celsius or 20.7 Celsius.

Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.
