Answer:

A scientific method is the one which is independent of the person taking the measurements. Hence, a method which includes a scientific instrument/experiment, systematic observation, measurement, testing etc. and is independent of personal feelings or opinions is known as a scientific method.

The measurement of temperature, testing of the material of surface, and moisture content in the atmosphere are testable questions and part of scientific method to find the reasons of different shapes of dewdrops. whether the different shapes are formed due to change in temperature, surface or moisture content in the atmosphere or not? The result of this measurement would not depend on the scientist doing the experiment. Scientific instruments would be used which would give the same reading. But the result of the observation of most unusual shape and pleasing shape of drop is purely dependent on one observer.A scientific method is the one which is independent of the person taking the measurements. Hence, a method which includes a scientific instrument/experiment, systematic observation, measurement, testing etc and is independent of personal feelings or opinions is known as a scientific method.

How does a sample of hydrogen at 10 °C compare to a sample of hydrogen at 350 K?
Aleks04 [339]

Answer: -

The hydrogen at 10 °C has slower-moving molecules than the sample at 350 K.

Explanation: -

Temperature of the hydrogen gas first sample = 10 °C.

Temperature in kelvin scale of the first sample = 10 + 273 = 283 K

For the second sample, the temperature is 350 K.

Thus we see the second sample of the hydrogen gas more temperature than the first sample.

We know from the kinetic theory of gases that

The kinetic energy of gas molecules increases with the increase in temperature of the gas. The speed of the movement of gas molecules also increase with the increase in kinetic energy.

So higher the temperature of a gas, more is the kinetic energy and more is the movement speed of the gas molecules.

Thus the hydrogen at 10 °C has slower-moving molecules than the sample at 350 K.

The octane number of gasoline is a measure of octane activity. The octane activity is determined by comparing the engine perform
Semmy [17]

Answer:

A. True

Explanation:

The octane number is determined by comparing the characteristics of gasoline to isooctane (2,2,4-trimethylpentane) and heptane. The correct option is option A.

Basically, the higher the octane  number, the  greater the resistance of the gasoline to knocking.
