Can someone convert 150 cm of copper (Cu) wire into mm of Cu wire?​
Vedmedyk [2.9K]

1500 mm of copper wire are produced by converting 150 cm of copper wire.

The following is the centimeter to millimeter conversion factor: 1 cm is equivalent to 10 mm.

Consequently, 150 cm will equal 150 x 10 = 1500 mm.

  • The multi-step process of unit conversion involves multiplying or dividing by a numerical factor.
  • Unit conversion is the process of converting the measurement of a given amount between various units, often by multiplicative conversion factors that alter the value of the measured quantity without altering its effects.
  • Unit conversion is a multi-step procedure that involves adding, subtracting, multiplying, or dividing by a conversion factor.

In the experiment involving hydrated copper sulfate, overheating causes a high calculated percent value for water. why is the hi
Strike441 [17]
The answer to this question would be: Because the increase of temperature will increase volume.

Using PV=nRT formula we can see that temperature increase will cause an increase in volume. Overheating will cause the volume increase, then increasing the volume. If the percent value used is based on the volume, it will seem that the water is increased. But if the percent is using mass, there will be no increases.
That is why sometimes scientists using molality in a reaction with high temperature changes.
