1 Silver solder is an alloy of silver, copper, and sometimes a little zinc. 2  It comes in three main grades-Hard, Medium, and Easy. 3  Hard melts at the highest temperature, Easy at the lowest. 4  For this Instructable, I used Medium as my torch is a bit small to melt Hard very quickly.
From these two formulas we can see that if the speed doubles, then the kinetic energy of an object becomes four times larger. Lets see an example: A car has a speed of 4 metres per second. Its kinetic energy is KE=1/2mass by speed squared, so its KE=1/2mass by 16 (since the square of 4 is 16). If the speed doubles and the car does 8 metres per second, its kinetic energy is: KE=1/2mass by 64 (since 8 squared gives us 64). If we divide 64/16 its 4. So we see that when speed doubles, the Kinetic Energy of an object becomes four times larger. Answer: Speed is distance over time (V=x/t).
Any increase in the frequency of collisions with the walls must lead to an increase in the pressure of the gas. Thus, the pressure of a gas becomes larger as the volume of the gas becomes smaller. Charles' Law (V T). The average kinetic energy of the particles in a gas is proportional to the temperature of the gas. Because the mass of these particles is constant, the particles must move faster as the gas becomes warmer.
