Suppose the thermometer you used in your Charles's law experiment consistently gave low temperature readings. How would that influence the value of k' you would obtain?
a. Make it too high.
b. Make it too low.
c. Would not influence it.
Homework Answers
Charles law give the relationship between temperature and volume.
It is found that on constant temperature the volume of fixed mass of gas is directly proportional to its absolute temperature .
V= kT
Or k= (V/T)
The value of k depends on volume and temperature.
So in thermometer temperature decreasing constantly so to make the k constant volume will also decrease.
Hence there won't be any influence in the value of k
It is a constant .
Answer = (c)

Suppose you use a miscalibrated thermometer that reads 1.0 degree C higher than the actual temperature throughout the entire experiment. Consider how the miscalibration affects each temperature measurement, and then determine what happens to your T_f values. What would be the overall effect on your molecular weight calculations? Suppose a small amount of your solid sample is lost and does not get dissolved in the solvent. How does this affect your number of solute moles and your molality? What happens...

Will it be too high, too low, or have no effect on the result? explain your answer. a. the balance used to determine the mass of the metal was in error by 10g on the high side. In other words, the balance gave a larger mass than the true mass. b. it was thought that the metal was in the boiling water long...
