Neporo4naja [7]

1)  Dalton stated that atom is matter that can not be divided, but it is proved that the atom can be divided into subatomic particles  (electrons, protons and neutrons).

2) He stated that atoms of one element can not be changed into atoms of other  elements, but now that is possible by nuclear reactions.

Today we still use his postulate: Atoms combine in the ratio of small whole numbers to form stable compounds, for example H₂O.

Explain the working principle of a clinical thermometer ​
bagirrra123 [75]

Answer:

A clinical thermometer is a thermometer used to measure human body temperature. Most made in the 20th century are mercury-in-glass thermometers. They are accurate and sensitive, having a narrow place where the mercury level rises very fast. A kink in the tube stops the mercury level from falling on its own.

If a gas has a volume of 750 mL at 25°c, what would the volume of the gas be at 55°c?
Airida [17]

825.5mL

To find this, use the equation \frac{V1}{T1} = \frac{V2}{T2}

Make sure to convert all temperatures in Celsius to Kelvin by adding 273. Once you do that, multiply and divide accordingly to get the final answer of 825.5mL

Hope this helps!
