Please Help! 100 Points! Look at the two thermometers.
Which statement explains which thermometer is more appropriate to measure the temperature of a liquid at 47 °C?

Thermometer C, because it measures accurately to the tens place.
Thermometer D, because it measures accurately to the tens place.
Thermometer C, because it measures accurately to the ones place.
Thermometer D, because it measures accurately to the ones place.

A

Explanation:

Accuracy : It is defined as the closeness of a measured value to a standard or known value.

For Example : If the mass of a substance is 50 kg and one person weighed 48 kg and another person weighed 55 kg. Then, the weight measured by first person is more accurate.

Precision : It is defined as the closeness of two or more measurements to each other.

For Example : If you weigh a given substance five times and you get 1.8 kg each time. Then the measurement is said to be precise.

The level of precision is determined by the maximum number of decimal places.

As we are given that the measurement of the temperature of a liquid at .

From the given thermometer we conclude that, the thermometer A is more appropriate than the thermometer B because in thermometer A there are 10 divisions between the two temperature and the smallest division is, 0.1.

So, the temperature of liquid will be,

idk what the question is about

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.
