Hey there :)
We can see that the solubility of salt increases with increasing temperature. This happens with most substances.
To find out the maximum mass of copper sulfate that can be dissolved in water at these temperatures, just interpret the graph.
Considering Y-axis as g copper sulfate/100 g water and the X-axis as the temperature in °C:-
<u>1)</u>
a: <u>0 °C - 14 g of copper sulfate/100 g of water</u>
b: <u>50 °C - 34 g of copper sulfate/100 g of water</u>
c: <u>90 °C - 66 g of copper sulfate/100 g of </u><u>water</u>
<u>2)</u> From the graph, we can infer that temperature affects the solubility of the salt.

Answer:
Universal indicator can show us how strongly acidic or alkaline a solution is, not just that the solution is acidic or alkaline. This is measured using the pH scale , which runs from pH 0 to pH 14.

The option which accurately defines kinetic energy from the choices above is:
the energy an object has because of its motion
The correct answer choice is option c
In order words, kinetic energy is that type of energy which a body or an object posess due to its relative motion.
<h3>What is energy?</h3>
Energy can simply be defined as the capacity of doing work.
Energy is a derived quantity; meaning that it is obtained from the combination of fundamental quantities.
The unit of energy joules.
Other examples of derived quantities just like energy too are:
- Volume
- Speed
- Acceleration
- Density.
- Upthrust
- Momentum
- Momentum
- Power
- Pressure
- Force
Below are some few forms of energy; these are:
- Kinetic energy
- Potential energy
- Mechanical energy
- Solar energy
- Light energy
- Chemical energy
So therefore, the option which accurately defines kinetic energy from the choices above is:
the energy an object has because of its motion
