1) Some roads use concrete plates, leaving gaps between these plates. This construction is used because of thermal expansion. Assuming that the gaps are closed when the temperature is 130 degrees Fahrenheit what is the relative change of the length of these plates when the temperature goes down to -40 degrees Fahrenheit in deep winter? (You can assume that we're dealing with the linear approximation.)

Required information In an emergency, it is sometimes the practice of medical professionals to immerse a patient who suffers from heat stroke in an ice bath, a mixture of ice and water in equilibrium at 0°C, in order to reduce her body temperature. The average specific heat of human tissue at 20.0°C is 3.50 x 103 J/kg-K. The latent heat of fusion for water is 333.7 x 10 J/kg. A(n) 85.1-kg patient whose body temperature is 43.5°C was reduced to 37.0°C. If she is placed in a bath containing 5.70 kg of ice, what will be the ice remaining in the bath when her body temperature is 37.O°C? kg

3. A 3.2 m length of copper pipe extends directly from a hot-water heater in a basement to a faucet on the first floor of a house. If the faucet isn't fixed in place, how much will it rise when the pipe is heated from 20.0° C to 85.9° C. The coefficient of linear expansion for copper is 1.6*10-5 K−1.

A food product containing 80% moisture content is being frozen. Estimate the specific heat of the product at -6 ° C when 80% of the water is frozen. The specific heat of the dry product is 2 kJ / (kg ° C). it is assumed that the specific heat of water at -10 ° C is the same as the specific heat of water at 0 ° C, and the specific heat of ice follows the function Cp ice = 0.0062 Freezing point + 2.0649. Cp of frozen product = .... kJ / kg ° C.
