Thermocouple and Food Lab Procedures

The video tutorial guides students through a food lab experiment. It begins with setting up the equipment, including weighing a can and adding water. Students then use a temperature probe and thermocouple to measure temperature changes as a food item is ignited. The tutorial emphasizes safety precautions, such as keeping the thermocouple away from direct contact. Students are instructed to monitor temperature changes until a high point is reached, then reset the setup for additional trials.

What is the first step in setting up the food lab experiment?

• Add water to the can

• Weigh the can and record the mass

• Insert the temperature probe

• Tie the can to the ring

How much water should be added to the can?

• 75 milliliters

• 25 milliliters

• 100 milliliters

• 50 milliliters

Where should the temperature probe be placed?

• In the can

• In the air

• On the sand

• In the fire

What is the role of the thermocouple in the experiment?

• To go into the fire with the food

• To measure the mass of the can

• To add water to the can

• To record the sand temperature

What should you observe when the food ignites?

• The weight of the can

• The position of the thermocouple

• The change in color of the flame

• The amount of water left

Why is it important not to touch the tip of the thermocouple?

• It will break

• It will burn you

• It will cool down

• It will change color

What should you do when the high temperature no longer increases?

• Add more water

• Change the food item

• Remove the can

• Record the high point

At what temperature does the food start burning in the Bunsen burner?

• 250 degrees

• 200 degrees

• 150 degrees

• 100 degrees

What is the final step after burning each food item?

• Weigh the burnt food

• Add more sand

• Increase the flame

• Change the thermocouple
