3. (honors) the heat will transfer from the hot object to the cold objects. think
about what that
what will the equilibrium temperature be when a 270g block of copper at 300°c
is placed in a 150-g aluminum calorimeter cup containing 820-g of water at
12.0°c (the cup and the water are at equilibrium before the metal is added). the
specific heat of copper is 0.093 cal/g°c and the specific heat of aluminum is 0.22
cal/g°c.

A30 kg weight lies on top of a massless piston of area a = 0.01 m2 the exterior air is at a (constant) p =1 atm and t = 27 c. the interior gas is 0.4 moles of (ideal) n2 and it has initial temperature 27.00 degrees c. 1. what is the initial pressure in the interior? a. 29.4 kpa b. 130.7 kpa c. 101.3 kpa the next three questions concern what happens when an amount of heat q is slowly added to the interior, raising the piston by 1 mm and raising the interior temperature to 27.40 c

The difference between a red shift and a blue shift has to do with wavelength frequency. t or f
