Question

In a container of negligible mass, 0.300 kg of ice at an
initial temperature of -25.0°C is mixed with a mass m
of water that has an initial temperature of 80.0°C. No
heat is lost to the surroundings.
Part A
If the final temperature of the system is 19.0°C, what is the mass m of the water that was initially at 80.0°C?

Just about everyone at one time or another has been burned by hot water or steam. This problem compares the heat input to your skin from steam as opposed to hot water at the same temperature. Part C How much heat Assume that water and steam, initially at 100° C, are cooled down to skin temperature, 34° C, when they come in contact with your skin. Assume that the steam condenses extremely fast. The heat capacity of liquid water is c = Q2 is transferred to the skin by 25.0 g of steam onto the skin? The heat of 4190 J/(kg · K). vaporization for steam is L = 2.256 × 10® J/kg.

The basal metabolic rate is the rate at which energy is produced in the body when a person is at rest. A 75 kgkg (165 lblb) person of height 1.85 mm (6.07 ftft) would have a body surface area of approximately 2.00 m2m2. Part A What is the net amount of heat this person could radiate per second into a room at 17.0 ∘C∘C (about 62.6 ∘F∘F) if his skin's surface temperature is 31.0 ∘C∘C? (At such temperatures, nearly all the heat is infrared radiation, for which the body's emissivity is 1.0, regardless of the amount of pigment.) Express your answer with the appropriate units. HnetHnet = nothingnothing SubmitRequest Answer Part B Normally, 80%% of the energy produced by metabolism goes into heat, while the rest goes into things like pumping blood and repairing cells. Also normally, a person at rest can get rid of this excess heat just through radiation. Use your answer to part A to find this person's basal metabolic rate…
Learning Goal: To understand the ideal gas law and be able to apply it to a wide variety of situations. The absolute temperature T. volume V, and pressure p of a gas sample are related by the ideal gas law, which states that pV=nRT. Here is the number of moles in the gas sample and R is a gas constant that applies to all gases. This empirical law describes gases well only if they are sufficiently dilute and at a sufficiently high temperature that they are not on the verge of condensing. In applying the ideal gas law, p must be the absolute pressure, measured with respect to vacuum and not with respect to atmospheric pressure, and I must be the absolute temperature, measured in kelvins (that is, with respect to absolute zero, defined throughout this tutorial as -273° C). If p is in pascals and V is in cubic meters, use R = 8.3145 J/(mol-K). If p is in atmospheres and V is in liters, use R = 0.08206 L-atm/(mol-K) instead.
