Question

A thermometer is placed in a beaker full of water that has been sitting on the lab table for a few hours. The beaker is placed on a ring stand and heated over a Bunsen burner for 4 minutes. After 4 minutes, the temperature is taken again. Find the temperature change of the water if the temperature of the room is 26°C.

A)26°CB)73°CC)99°CD)124°C

Answer 1

B 73 degress celcius

Step-by-step explanation:

Answer 2

Based on the information I would assume B, 73 degrees...

It shouldn't be A, 4 minutes on the burner should increase the temperature.

If it were D, it would be beyond boiling, and water takes a decent amount of energy to heat, D should be all vapor.

Same logic for C, it's basically almost boiling.

I would say 73 degrees seems most reasonable for 4 minutes.
