Dew Point and Temperature Experiment

Cameron Martis, a UTA for ATM 101, conducts a lab on measuring atmospheric moisture. The lab involves determining the dew point and relative humidity in a room. The experiment begins by setting up temperature probes in water and air. Water is cooled using ice to observe condensation, indicating the dew point. The dew point is found to be approximately 2.7°C.

What is the primary objective of the lab conducted by Cameron Martis?

• To find the boiling point of water

• To calculate the air pressure in the room

• To determine the dew point and relative humidity

• To measure the speed of sound in air

What is the initial temperature of the water used in the experiment?

• 19.4°C

• 26.8°C

• 21.1°C

• 10.9°C

Why is it important to let the temperature probe come to equilibrium with the water?

• To freeze the water

• To make the water boil

• To change the water's color

• To ensure accurate temperature readings

What is the room temperature during the experiment?

• 5.2°C

• 21.1°C

• 19.4°C

• 26.9°C

Why is ice added to the water during the experiment?

• To change the color of the water

• To make the water evaporate faster

• To increase the water temperature

• To decrease the water temperature and observe dew formation

At what temperature does the water reach when the first check for condensation is made?

• 10.9°C

• 4.8°C

• 18.6°C

• 9.9°C

What tool is used to check for dew on the jar?

• A ruler

• A magnifying glass

• A flashlight

• A thermometer

What happens to the temperature of the water as more ice is added?

• It fluctuates randomly

• It increases

• It decreases

• It remains constant

What is the final dew point temperature determined in the experiment?

• 6.4°C

• 2.7°C

• 4.3°C

• 9.4°C

What is the significance of the dew point in atmospheric studies?

• It helps in determining the relative humidity

• It indicates the boiling point of water

• It measures the air pressure

• It shows the wind speed
