It is proposed to use a katharometer to measure the amount (about

5%) of oxygen in nitrogen, in the presence of a small amount (0.5%)

hydrogen. How constant would the proportion of hydrogen have to

be in order to limit errors in measurement of % oxygen to + 0.1%?

The thermal conductivities are:

nitrogen 0.993

oxygen 1.052

hydrogen 6.993

True or​ False: The best measure to use when comparing alternative investments is the amount of the dollar gain or loss. With holding periods of more than a​ year, annualizing the HPR makes it smaller. The lower the correlation coefficient between two​ stocks, the greater will be the benefit from diversifying by combining the two stocks in a portfolio. Based on the period 1950​ – 1999, you would have the less uncertainty about any expected return on small company stocks...

One measure of the state of the economy is the amount of money homeowners pay on their mortgage each month. To determine the extent of change between this year and 5 years ago, a random sample of 150 homeowners was drawn. The monthly mortgage payments for each homeowner for this year and for 5 years ago was recorded (the amounts were adjusted so that we could compare constant dollars). One would like to use the data to estimate the mean...

1 In the absence of oxygen, cells consume glucose at a high, steady rate. When oxygen is added, glucose consumption drops precipitously and is then maintained at the lower rate. Why is glucose consumed at a high rate in the absence of oxygen and at a low rate in its presence? 2 In the following diagram showing the distribution of thermal energy in a population of substrate molecules, the energy thresholds indicated by numbers represent ...

Fish and wildlife managers have determined that a sudden temperature increase greater than 5°C would be harmful to the marine ecosystem of a river. Warmer waters contain less dissolved oxygen and cause organisms in a river to increase their metabolism; if the temperature increase is sudden, the organisms do not have time to adapt to the new environment and likely will die. (Changes in river temperatures of five degrees and more due to seasonal temperature variations are common, but those...

Background Almost all animal and plant cells require oxygen and give off carbon dioxide. This is called gas exchange and it occurs by passive diffusion. Some animals do all or most of their gas exchange across their skin (for example amphibians) but they have very low metabolisms and use very little oxygen and get rid of very little carbon dioxide. On the other hand humans (and other mammals) have very high metabolic requirements and we can’t rely on gas exchange...

Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that a random sample of 43 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (milliliters plasma per kilogram body weight). Assume that σ = 7.70 ml/kg for the distribution of blood plasma. (b) What conditions...
