Imagine you have two beakers. both beakers are filled with the same amount of water. the water in both beakers is the same temperature as well. you add 50 g of substance a to the first beaker, and 50 g of substance b to the second beaker. after stirring both beakers, there is a small pile of substance a at the bottom of the first beaker. none of substance b is visible in the second beaker. which of the following statements is true? a. substance a is less soluble in water than substance b. b. substance a is more soluble in water than substance b. c. substance a is not soluble in water. d. substance b is not soluble in water.
a change of 1 °f
i have never heard of a thomson degree. i presume it is the same as 1 k, because the british physicist william thomson is better known as lord kelvin, who invented the kelvin scale.
although the kelvin and celsius scales have different definitions, 1 k is the size as 1 °c.
on the celsius scale, the difference between the boiling point and freezing point of water is divided into 100 °.
on the fahrenheit scale, the same difference is divided into 180 °.
thus, a fahrenheit degree represents the smallest temperature change.
there are many different forms of energy present in a classroom.
kinetic energy (energy of motion) may be seen in students walking around the classroom.
light/radiant energy may be seen from the lights on the ceiling.
potential energy (stored energy) may be seen in books on high shelves.
