Write down the conservation of energy equation for heat when a mass of ice, at a temperature less than 0℃ (T1), is added to a copper (Cu) container holding some hot water, at a temperature less than 100℃ (T2) . Underneath each term indicate the process involved, e.g. ice warms (Q1), ice melts (Q2), water that was ice warms (Q3), hot water cools (Q4), copper container cools (Q5). Your equation must contain all these variables mice,mwater,mCu,cice, cwater, cCu and Lf; the initial temperatures T1 and T2; and the final equilibrium temperature T3.

USING CONSERVATION OF ENERGY AND WORK ENERGY PRINCIPLE:
A block of mass m=1.8 kg on a table is pushed against a spring
that has a force constant of k=250 N/m, compressing it 20 cm (the
block is not attached to the spring). The block is then released,
and the spring pushes the block to move to the right. The
coefficient of kinetic friction between the block and the table is
0.45.
(a) Find the distance the block will travel before...
