. Two containers of volumes V 1 and V 2 are connected by a small tube with a valve. Initially, the valve is closed and the two volumes contain monoatomic gas at pressures P 1 and P 2 , and temperature T 1 and T 2 respectively. The initial values are given by: V 1 =24.942 I , P 1 =3.13 bar , T 1 =40^ C , V 2 =49.884 L , P 2 =24.01 bat , T 2 =70^ C . The valve is then opened, and an amount of heat of 111.68 k. J is acquired by the gas. 2. Calculate the final pressure of the gas

iron would move it is magnetic there is a mag field around the current in the wire

laticia draws the diagram below to show earth’s magnetic field.

answer

the arrows to the right of earth should point up.

the best answer for these questions would be:
