a student conducts an experiment to determine how the temperature of water affects the time for salt to dissolve in 100 ml of water. the student makes one measurement for each temperature.what is one way that the student could improve the experiment?perform multiple trials for each measurement instead of just oneperform multiple trials for each measurement instead of just oneuse a different type of salt for each temperature of wateruse a different type of salt for each temperature of waterperform one trial for each measurement but use a different volume of water for each testperform one trial for each measurement but use a different volume of water for each testuse a different timer for each temperature of water

Sagot :

"perform multipule trials for each measurment instead of just one"  is the way that student can improve the experiment.

How is water's temperature determined?

  • A thermistor, a metallic instrument that experiences a predictable change in resistance in response to temperature variations, can be used to monitor the temperature of water.
  • A readout of the temperature in Celsius, Fahrenheit, or Kelvin is obtained by measuring and converting this resistance.
  • Water should be consumed at room temperature (20°C/68°F) for optimum flavour or chilled to 6°C/43°F for maximum cooling.

Why is water temperature important?

Because it controls the sorts and types of aquatic life, limits the maximum dissolved oxygen concentration of the water, and affects the speed of chemical and biological reactions, temperature is a crucial water quality and environmental characteristic.
