4. A well-insulated styrofoam bucket contains 143 g of ice at 0 °C. If 21 g of steam at 100 °C is injected into the bucket, what is the final equilibrium temperature of the system?(cwater=4186 J/kg.°C, Lf=3.35 × 10° J/kg, Ly=2.26 × 10° J/kg) °C

A 0.075-kg ice cube at -30.0°C is placed in 0.375 kg of 35.0°C water in a very well-insulated container. The latent heat of fusion for water is Lf = 79.8 kcal/kg. Part A: What is the final temperature of the water, in degrees Celsius?

An ideal gas enclosed in a 1.77ft3 rigid tank initially at 70°C and 0.92kg/cm2 . Find the temperature in °C if the final pressure is 72in Hg.a. 692.6699 0C b. 682.2848 0C c. 633.5381 0C d. 644.0674 0C

A chunk of hot iron is pulled out of a fire and placed between aluminum vice grips.  The mass of the iron is 219 g and the mass of the aluminum is 66.4 g.  The iron is initially 351.8 °C.  The aluminum is initially 24.7 °C.  Assuming no loss of heat to the environment, what is the final temperature of the iron-aluminum system? I couldn't even get started on this one.

10. Concrete sidewalks are always laid in sections, with gaps between each section. For example, the figure shows five identical 5.70-m sections, the outer two of which are against immovable walls. The four identical gaps between the sections are provided so that thermal expansion will not create the thermal stress that could lead to cracks. What is the minimum gap width necessary to account for an increase in temperature of 38 °C? cm Gap il6 ccil6 ccil6 cci16. 116 cci16 cci16 ceil6 ceil6 ccil6 ce écile 6 cc 16 ceil6 cci16 ceit 116 cci16 ceicci16 cci16 cci16 ceil ceil6 ccil6 ccil6 cei16

The initial temperature of the water and calorimeter is 17 °C, and the final temperature after equilibrium is established is 37 °C. When the calorimeter and its contents are weighed, 32.0 g of water are found to have evaporated. What was the temperature T?(Cw = 4186 J/(kg. °C), L=3.35 x 105 J/kg, Ly=2.26 × 106 J/kg, Ccopper = 387 J/(kg.°C) #3 X 20 E D $ A t 4 C F4 R TI F % 5 °C V M F5 T G ^ 6 MacBook Air B SA F6 Y & 7 H AA F7 C N * 8 c DII FB M ( 9 CO K DD F9 O ) V O F10 11 F11 F12 :l P{ DEEL 201

14. Most automobiles have a coolant reservoir to catch radiator fluid that may overflow when the engine is hot. A radiator is made of copper and is filled to its 12-L capacity when at 10°C. What volume of radiator fluid will overflow when the radiator fluid reach their 95°C operating temperature, given that the fluids volume coefficient of expansion is B= 400X10^-6/°C? Note that this coefficient is approximate, because most car radiators have operating temperatures of greater than 95° C. The volume coefficient of expansion of copper is 5.1X10^-5 /°C. Hint:consider the expansions of both the fluid and the radiator.
