Which THREE are examples of heat transfer via convection?


Deep frying a turkey


Heat lamp at McDonald's over the fries


Burning your legs on a hot car seat (assume the car's interior is black, it is parked in the sun , and that you are wearing shorts.)


Fanning yourself with a notebook to cool off when the school's air conditioner breaks for the 3rd time in a month


Feeling the sun warm your skin


Baking brownies in an air fryer


Over cooking a Hot Pocket in the microwave


Melting crayons with a hot iron


Using a surface temperature sensor to determine the
T of an aluminum track.

Answer 1

The three examples of heat transfer via convection from your list are:

1. **Deep frying a turkey** - This involves the transfer of heat through the oil, which circulates around the turkey as it cooks.

2. **Fanning yourself with a notebook to cool off when the school's air conditioner breaks for the 3rd time in a month** - When you fan yourself, you are moving air over your skin, increasing heat transfer from your body to the air via convection.

3. **Heat lamp at McDonald's over the fries** - While the lamp emits infrared radiation, it causes the air around the fries to heat up, which then transfers heat to the fries through convection.

The other options involve heat transfer through conduction or radiation rather than convection.
