The question is incomplete, here is a complete question.
An arctic weather balloon is filled with 27.8 L of helium gas inside a prep shed. The temperature inside the shed is 13 ⁰C. The balloon is then taken outside, where the temperature is -9 ⁰C. Calculate the new volume of the balloon. You may assume the pressure on the balloon stays constant at exactly 1 atm. Be sure your answer has the correct number of significant digits.
Answer : The new volume of the balloon is 25.7 L
Explanation :
Charles's Law : It is defined as the volume of the gas is directly proportional to the temperature of the gas at constant pressure and number of moles.
or,
where,
= initial volume of gas = 27.8 L
= final volume of gas = ?
= initial temperature of gas = 
= final temperature of gas = 
Now put all the given values in the above equation, we get:
Therefore, the new volume of the balloon is 25.7 L
Copyright is a form intellectual property protection.
This serves to protect the original works of authorship including literary,
musical, and dramatic works. This differs to patent since copyright is for
artistic works and patent is for inventions.
A copyright lifespan is equivalent to the life of the
author plus 70 years. The only circumstance in which the author loses the copyright
protection is when the product is sold to another person/company.
Answer: <span>The
author sells the work to another person/company</span>
The force due to friction is generally independent of the contact area between the two surfaces. This implies regardless of whether you have two overwhelming objects of a similar mass, where one is half as long and twice as high as the other one, despite everything they experience the equivalent frictional power when you drag them over the ground.
