A sample of gas is put into a container with a movable piston that will allow pressure to be maintained. If the sample of gas was initially at 6.50 degrees Celsius and occupied a volume of 11.7 L, what temperature would the sample be if the piston changed the volume to 89.1 L?

2129.72 K

Explanation:

In this experiment, both the amount of gas and the pressure remain constant.

Those are the conditions for Charles' law:

For this problem:

We need to calculate T₂, but first we'll convert 6.50 °C to K:

Now we input the data on the equation:

And solve for T₂:

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
