The Sanchez family just got a new pool. The pool company showed them the location of the heater, which is in one corner of the deep end. How does the heater in one corner of the pool, heat the entire pool? (1 point)
• The heater warms the air above the pool, which warms the water
The heater warms the concrete walls of the pool, which warms the water.
• The heater adds thermal energy evenly to the pool's water
• The heater creates convections currents, which transfer warmer water away from the heater and cooler water
