3. A 200cm glass flask is filled to the brim with mercury (BH = 18 x 10-5 K-1) at 20 C. HOW much mercury overflows when the temperature of the system is raised to 100 C? The coefficient of linear expansion of the glass is 0.40 x 10-5 K-1.A camper pours 0.300 kg of coffee: initially in a pot at 70C into a 0.120kg aluminum cup initially at 20C. What is the equilibrium temperature? Assume that coffee has the same specic. heat as water and that no heat is exchanged with the surroundings. Cw: 4190 J wkg-K and CAT: 910 J rkg-K
