1. susie wondered if the height of a hole punched in the side of a quart-size milk carton would affect how far from the container a liquid would spurt when the carton was full of the liquid. she used 4 identical cartons and punched the same size hole in each. the hole was placed at a different height on one side of each of the containers. the height of the holes varied in increments of 5 cm, ranging from 5-20 cm from the base of the carton. she put her finger over the holes and filled the cartons to a height of 25 cm with a liquid. when each carton was filled the proper level, she placed it in the sink and removed her finger. susie measured how far away from the carton’s base the liquid had squirted when it hit the bottom of the sink.

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.
