What error would be introduced into the value of J in failing to take into acct the heat absorbed by the stirrer?
The error introduced by failing to account for the heat absorbed by the stirrer would result in an underestimate of the total heat absorbed by the system. This would lead to inaccuracies in calculating the final temperature change or total heat transfer in a calorimetry experiment. Taking into account the heat absorbed by the stirrer is crucial for obtaining accurate and precise results.
What error would be introduced into the value of J on failing to take into account the heat absorbed by the stirrer?
' J ' means Joules , unit for the amount of Energy in Physical Science... Heating Effect of Current ... Joule's Constant = Electrical Energy in Joules / Amount of Heat in calories Electrical Energy in Joules = Voltage in volts x Current in amperes x Time in seconds Amount of Heat in calories = Mass of Water x Specific Heat of Water x Change in Temperature of Water + Mass of Calorimeter x Specific Heat of Calorimeter x Change in Temperature of Calorimeter ANSWER: The Amount of Heat will be very hot and Joule's Constant will be too big which will make it not realistic as part of the experimental calculations. You must know that it is necessary to get the temperature in the state of equilibrium. Remember that, due to the use of the metal stirrer which absorbed the heat energy, the temperature of water inside the calorimeter had decreased partially or was delayed in rising up despite to the fact that the electrical energy generated is proportionally equal to the increase in temperature of the calorimeter.
Can you make a back scratcher from a paint stirrer?
An effect back scratcher can be made from a paint stirrer in three ways. 1. Scratch your back with the stirrer without changing it in any way. 2. Attach a soft scratcher (such as a scrubby) to the stirrer. 3. Carve the end of the stirrer into a usable shape.

Why magnetic stirrer does not move?
Possible reasons why a magnetic stirrer does not move could be: the magnetic bar is not properly placed or is stuck to the sides of the container, the stirrer speed is set too low, the stir plate is not turned on, or the stir bar is not strong enough to be rotated by the magnetic field.
What is used to swirl or mix solutions?
A stir bar or magnetic stirrer is commonly used to swirl or mix solutions in a laboratory setting. The stir bar is placed in the solution and is rotated by a magnetic field produced by the magnetic stirrer, resulting in thorough mixing.
