Lisa's Chemistry class was performing an experiment with gas pressures. They filled a container with gas at a pressure of 101,000 Pa at room temperature. When they doubled the temperature, the pressure also doubled. What was the new pressure in scientific notation?

2.02 × 10^5 Pa

Explanation:

According to this question, in an experiment, a container was filled with gas at pressure of 101,000 Pa, at room temperature. When this temperature was doubled, the pressure also increased by two times i.e.

The pressure changed to (101,000 Pa × 2) = 202,000 Pa

This question is asking to represent this in scientific notation. Scientific notation aims at representing a small or too large number in an easy way. It is done by making use of power of ten i.e. a × 10^b

Where; a = decimal number

b = power of ten

In the case of a large number like 202,000, the power of ten is derived by counting the decimal place backwards. If we are to count until we stop in front of the last digit, we will have 5 times.

That is; 2.02000 × 10^5

We can remove every trailing zeros

Hence, the answer is 2.02 × 10^5 Pa.

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools
