The melting point (in degrees Fahrenheit) for a randomly selected tub of margarine of a certain brand is known to have a normal distribution with a SD, σ = 1.21. A sample of n = 5 tubs of margarine is drawn. The sample mean of melting temperature is computed to be ¯x = 95.3. (a) Construct a 95% confidence interval for the mean melting temperature. (b) Construct a 99% confidence interval for the mean melting temperature. Compare the width of the two intervals in (a) and (b)? (c) Did you use the central limit theorem to construct the intervals in (a) and (b)? Explain.

Melting point of ferrocene = 171.5-172.6 degrees Celcius
Literature melting point of ferrocene = 172-174 degrees
Celcius
Melting point of acetylferrocene = 78.9-83.2 degrees Celcius
Literature melting point = 81-81 degrees Celcius
What do these melting points indicate about the purity and
identity of the ferrocene and acetylferrocene samples?

A
substance has a melting point of 20 degrees celsius and a heat of
fusion of 3.4*10^ 4 J/kg. The boiling point is 150 degrees celsius
and heat vaporization is 6.8*10^ 4 J/kg at a pressure of one
atmosphere. The specific heats for the solid,liquid and gaseous
phases are 600 J/kg , 1000 and 400. How much heat is required to
raise the temperature 1.90kg of this substance from -4 degrees
celsius to 106 degrees celsius at a pressure of...

Problem 3
The melting point of gold is known to be approximately
1,060 degrees centigrade. This is, of
course, an average figure, for unavoidable ‘experimental
error’ causes more or less variation
from this figure whenever the test is actually
performed. The best measure of these variations is
the standard deviation. Suppose this has been calculated
from a large series of tests (assume n =
100), and found to be 3 degrees centigrade. Due to the
recent increase in the price...

Although gallium is a solid at STP, it had a low melting point
(29.76 degrees Celsius) and a liquid density of 5.9 g/cm^3. If
liquid gallium is used as the barometric liquir instead of mercury,
how far would Ga(l) travel up the column when the barometer is
exposed to 1 atm pressure?

Write a program that displays a temperature conversion table for
degrees Celsius and degrees Fahrenheit. The table should include
rows for all temperatures between 0 and 100 degrees Celsius that
are multiples of 10 degrees Celsius. Include appropriate headings
on your columns. The formula for converting between degrees Celsius
and degrees Fahrenheit can be found on the internet.

(Python)
Write a code converting degrees in Fahrenheit to degrees
Kelvin, using this conversion equation
conversion from degrees Fahrenheit to
Celcius:
? = (? − 32) x 5/9
and then to degrees Kelvin:
? = ? + 273.15
with the following properties
1) the code should take into account that temperature in
degrees Kelvin cannot be smaller than zero. In other words, your
code should return 0 Kelvin as the smallest temperature for any
input value of degrees Fahrenheit).
