Final answer:
The atmospheric pressure on top of Mt. Everest can be calculated using the given lapse rate.
Step-by-step explanation:
The atmospheric pressure on top of Mt. Everest on a day when water boils there at a temperature of 70.0°C can be determined using the given information. At sea level, the atmospheric pressure is 1 atmosphere or approximately 101.3 kPa. The pressure decreases with increasing altitude, and the decrease in pressure can be estimated using the lapse rate. Therefore, the atmospheric pressure on top of Mt. Everest can be calculated by considering the decrease in pressure with altitude using the given lapse rate.
