Question

a metal spoon sits in a pot of boiling water. the spoon becomes warm. which types of heat transfer contribute to the increase in temperature of the spoon?
convection and radiation
convection and conduction
radiation and conduction
radiation only

Explanation:

Convection occurs as the boiling water circulates and transfers heat. Conduction happens when heat is transferred from the hot - water to the spoon and along the spoon's material. Radiation is negligible in this case as the main heat transfer mechanisms here are due to direct contact (conduction) and fluid motion (convection).

Answer:

B. Convection and conduction
