A student lab group is brainstorming the design of an experiment that uses a gas-filled balloon to determine how the temperature affects the volume of the gas. Which Post-it note describes the most effective design?

1) Inflate three different balloons to three different volumes. Get three different beakers and fill them with water having three different temperatures. Put the biggest balloon in the beaker with the hottest water and the smallest balloon in the beaker with the coldest water. Measure the volume of each balloon and the temperature of the water.
2) Inflate a balloon. Put it in a beaker of room temperature water. Measure the balloon’s volume and the temperature of the water. Place the same balloon in a beaker of very cold water. Wait 3 minutes. Measure the new volume of the balloon and the temperature of the water. Place the same balloon in a beaker of heated water. Wait 3 minutes. Measure the new volume of the balloon and the temperature of the water.
3) Inflate a balloon. Put it in a beaker of water. Measure the volume of the balloon and the temperature of the water. Inflate a different balloon. Put the balloon in the same beaker and measure volume and temperature. Repeat the procedure for a third balloon. Make sure that each balloon is inflated to a different volume each time you blow into it.
4)Inflate three different balloons so that they have different volumes. Prepare three beakers with water having a different temperature. Place the balloons in the water. Measure the volume of the water in the beaker and the temperature of the water in each beaker.

A3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular? a 3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular?
