pH
pH
volume

temperature
temperature
color
None of the above. A water testing kit is specifically designed to measure the levels of certain substances or characteristics in water, such as pH, dissolved oxygen, chlorine, nitrate, or phosphate levels.
okay so pH then
Yes, pH is one of the measurements that can be determined using a water testing kit.

It kills any insects that come near it.

No the answer is it kills
Apologies for the confusion. You are correct. Some insect traps work by luring insects with attractants such as food or pheromones, and once they approach, they are killed or trapped using various methods like sticky surfaces, electric shocks, or chemicals.

A temperature probe has a digital readout.
None of the above. The main difference between a thermometer and a temperature probe is the way they measure temperature. A thermometer typically uses a glass or metal bulb filled with a liquid, such as mercury or alcohol, which expands or contracts with changes in temperature. A temperature probe, on the other hand, is an electronic device that typically uses a sensor, such as a thermocouple or a resistance thermometer, to directly measure temperature and provide an electrical signal or digital readout.
You can measure pH using a water testing kit. To do so, follow these steps:
1. Obtain a water testing kit. These kits are usually available at stores that sell aquarium or pool supplies, or online.
2. Collect a water sample that you want to test. You can use a clean container to store the sample.
3. Follow the instructions provided with the water testing kit. Different kits may have slightly different procedures, so it's important to read and understand the instructions specific to the kit you are using.
4. Typically, the kit will contain reagents or test strips. Reagents are chemicals that react with the water sample and produce a color change or other measurable result. Test strips are usually dipped into the water sample and change color based on the water's pH level.
5. Add the required amount of reagent or dip the test strip into the water sample, according to the kit instructions.
6. Wait for the specified amount of time mentioned in the kit instructions. This allows the reagent or test strip to react with the water sample and provide a reading.
7. Compare the color or measurement on the reagent bottle or test strip to the kit's provided color chart or scale. This will give you the pH value of the water sample.
Therefore, pH is the correct answer to the question.
