Classify each example as conduction, convection, or radiation. DRAG &DROP THE ANSWER The top floor of a house is the warmest due to heat rising. __ You are stirring a bowl of hot soup with a metal spoon and the spoon starts to feel warmer. __ Sitting in your car after a long day and the seat burns __ you when you sit down. The kitchen gets warm when someone uses the stove because the stove heats up the air molecules that __ it. The Sun's light heats Earth's surface. You buy a lava lamp from the store.As the lamp heats up, blobs of hot liquid rise to the top and cold fliquids sink back down to the bottom. Conduction Radiation square

Callie and Jeff were investigating the effects of heat on chocolate. Chocolate barAwas left outside in the direct sunlight. Chocolate bar B was left inside with no direct sunlight. Which explanation BEST describes what happened to chocolate bar A? A Heat was transferred to the chocolate bar by evaporation causing it to melt. B Heat was transferred to the chocolate bar by radiation causing it to melt. C Heat was transferred to the chocolate bar by convection causing it to melt. D Heat was transferred to the chocolate bar by condensation causing it to melt.

The pressure exerted on a table by a brick is 180N/m^2 and the area of the base of the brick is 0.03m^2 Calculate the force, in N, that the brick exerts on the table.

Select the statements which are true about driving around a large, slow moving vehicle. Rocks or debris can be propelled from the tractor's large tire treads. You can drive close to the tractor since it is traveling under 25 mathrm(mph) . Tractors do not have or create large blind spots. You can pass the tractor on this road if this is a dashed white line. You should pass on the right shoulder to avoid an accident in the left lane if you want to pass. You can pass this tractor on a dashed yellow line if no traffic is approaching from the other direction.
