The easiest way to approximate ph level is through the ph paper measurement system because using pH paper would be best for doing a quick measurement in the field. It does not essentially need to be calibrated or standardized and the papers make available an instant estimate.
Answer:
Explanation:
Given
mass of ice
Final temperature of liquid
Specific heat of water
Latent heat of fusion
Latent heat of vaporization
Suppose M is the mass of steam at
Heat required to melt ice and convert it to water at
Heat released by steam
and must be equal as the heat gained by ice is equal to Heat released by steam
Answer: number of bacteria
Explanation:
A easier way. I like to remember it is that x axis = independent and yaxis = dependent variable, but if that doesn’t help think about this
Why would the number of bacteria effect the amount of time. It doesn’t make sense because time goes on forever and nothing can change about it but time can change the number of bacteria because if you had a timer of 30 seconds and the bacteria is for example 10 and if you had a timer of one minute then the number of bacteria change because of time, if you flip it, it doesn’t make sense
