Answer both or none -     0.52 mol of argon gas is admitted to an evacuated 3.00 liter (3.00 × 10-3 m3) container at 20.0°C. What is the pressure of the gas, in atm? 1.00 atm = 1.00×105 Pa. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

An arctic weather balloon is filled with 49.6L of helium gas inside a prep shed. The temperature inside the shed is 11.°C. The balloon is then taken outside, where the temperature is −39.°C. Calculate the new volume of the balloon.You may assume the pressure on the balloon stays constant at exactly 1atm. Round your answer to 3 significant digits.

A lead rod has a length of 60.6 m when the temperature is 12.4 degrees celsius. What is its length when the temperature is 51.2 degrees celsius? Note: Your answer must be in meters, however, do not include the unit, just enter the magnitude that correspond to the final length in meters. Round your answer to 2 decimal points Coefficient of linear expansion for lead = = 29 x 10-6 °C-¹

The area A of a rectangular plate is ab = 1.4 m?. Its coefficient of linear expansion is a = 22 x 10° /C°. After a temperature rise AT = 17°C, side a is longer by Aa and side b is longer by Ab (see the figure). Neglecting the small quantity (AaAb)/ab, find AA. %3D a Да Aa · Ab Ab
