Question

Chemistry Charles's Law \ Purpose of this experiment was to determine the number of degrees difference between 0 degrees Celsius and 0K.

1. A student doing this experiment was not very attentive to the experiment. Predict possible effects of the following situations, and state whether the situation would result in higher, lower, or unchanged value for Y.

(c.) The student used two different mercury thermometers during the experiment, one to measure the temperature of the boiling water in the beaker, and the other to measure the temperature of the water in the cold water bath.

(d.) The student closed the pinch clamp without equalizing the water levels inside and outside the flask, while it was resting on its side in the cooling bath.

Answer 1

Answer:

The relationship between Degree centigrade and Kelvin is,

0⁰C = 273 K

K = 273 + ⁰C

According to the Charles's Law

The Volume directly proportional to the Temperature.

V T

In the given experiment the volumes are not equal. That leads to the student observe the error in Temperature.

Thermometer resting on its side in the cooling bath:

To know the temperature of the water we have to dip the thermometer bulb in the water. Then the liquid in the bulb rises with the temperature.

If the thermometer is resting the side in the cooling bath the bulb and some part of the thermometer is exposed to the water and it does not give the accurate value. That means will get the higher value than the actual value.
