Kumar is studying how Earth is warmed by sunlight. The following illustration shows his model of the sun and Earth.

Which process is mostly responsible for warming the soil in Kumar’s model?

• Conduction between the lamp and the soil causes the soil to warm.

• Convection currents between the lamp and the soil cause the soil to warm.

• Expansion of particles in the soil causes the soil to warm.

• Radiation from the lamp reaches the soil and causes the soil to warm.

For a skillet, used for cooking, do you want a high or low specific heat

• High, so that it will need more energy to heat up
• Low, so that it will change temperature quickly

What would be the effect on the particles if more heat is supplied to the system?

• They would slow down
• They would stop moving
• They would speed up
• There would be no effect
