Question

when an open cup of water sits in a table, it will evaporate over gime. do all liquids evaporate at the same rate? suppose you conduct an experiment to see how quickly water, rubbing alcohol and bail polish remover evaporate. describe theee important techniques you will have to follow to make sure your experminal procedure is repeatable and objective.

Answer 1

Research Experiment

Abstract

The study is to investigate the rates of evaporation of liquids. It depends on the energy that the molecules possess. For the research, 4 beakers were filled with different liquids and made to stand for 7 days. The quantity left after the time period has elapsed determines the rate at which the liquids evaporate. Studying the individual characteristics of the liquids one could theorize the reason behind the varying rates of evaporation.

Introduction

The purpose of the experiment is to check whether different liquids evaporate at the same rate or not.

Problem Statement

Do all liquids evaporate at the same rate?

Hypothesis

Different liquids evaporate at different rates.

Materials

Orange juice

Alcohol

Nail polish remover

Water

4 beakers with graduations

Pen and paper

Step By Step Procedure

Pour 80 ml of each liquid in separate beakers.

Label the beakers with the names of the liquids

Place them in a dry location under room temperature.

Make a table on the paper to monitor the levels of the beaker for a week.
