Which is the best reason for choosing the beaker for heating the solution?

A
The beaker is the only container that can withstand high temperatures.
B
The beaker's wide mouth allows the thermometer to rest against the side.
C
The beaker will not tip over when placed on the hot plate.
D
The beaker is unbreakable.

Therefore the independent variable was pressuresolubility✔ temperature and the dependent variable was

Answers:
and the dependent variable was:temperature
.:volume

5

Which are ways to ensure that temperature readings are accurate? Check all that apply.

A
shaking the thermometer before use
B
using the thermometer as a stirring rod
C
making sure the liquid inside the thermometer is at eye level when taking the temperature
D
making sure the bulb of the thermometer does not touch the bottom of the beaker or the ice when taking the temperature
E
using the Celsius scale instead of the Fahrenheit scale when taking temperature readings

What is missing from the temperature and volume graph shown at right?

Answer:

The graph is missing a descriptive title (such as 'Temperature vs. Volume'), a label for the vertical axis (Volume in cm³), and specific units for the horizontal axis (Temperature in °C or K).

9

Check all items below that you mentioned were missing.a graph title, “Temperature vs. Volume”a label for the vertical axis, “Volume (cm³)”units for the horizontal axis

A
a graph title, “Temperature vs. Volume”
B
a label for the vertical axis, “Volume (cm³)”
C
units for the horizontal axis

Check all causes below that you mentioned.

A
The capillary tube was too close to the bottom of the beaker.
B
The ruler may have moved.
C
Water got into the capillary tube.
D
The temperature was not allowed to equilibrate in the 2-4 minutes.

Check all statements below that are true.

A
Heating air under the balloon will cause the air inside to expand.
B
The air inside will have the same mass but more volume.
C
Heating the air under the balloon will cause the entire balloon to rise.
D
The outside temperature will have no affect on the height of the balloon.
E
The only way to make the balloon sink is to let out the air.

Now do the same computation for all six pairs of values. What is the average of all six fractions V / T?

Answer:

0.0026

14

What might the student have done that caused this error? List all possible causes.

Answer:

The capillary tube may have been too close to the bottom of the beaker, the ruler may have moved, water may have entered the capillary tube, or the temperature may not have been allowed to equilibrate for 2–4 minutes.
