According to the kmt pressure is directly proportional to the number of collision between particles
Answer:
B. pOH = 14 - pH and D. pH = 14 - pOH.
Explanation:
Hello,
In this case, we must remember that pH and pOH are referred to a measure of acidity and basicity respectively, since pH accounts for the concentration of H⁺ and pOH for the concentration of OH⁻ in a solution. In such a way, since the maximum scale is 14, we say that the addition between the pH and pOH must be 14:
Therefore, the correct answers are B. pOH = 14 - pH and D. pH = 14 - pOH since the both of them are derived from the previous definition.
Best regards.
Answer:
Solenoid having iron core.
Explanation:
Solenoid having iron core will pick up more paperclips because this solenoid will produce more electromagnetism. Solenoid having no iron core produces lower magnetic field as compared to solenoid having iron core. The presence of iron in the core of solenoid increases magnetic field which leads to increase in electromagnetism so that's why the solenoid with iron core attract more paperclips as compared to no iron core solenoid.
Ionic bonds form when one atom gives up one or more electrons to another atom, so either the second or third one.
Answer:
If a one kilogram block of lead absorbs 2,000 J of energy then the temperature rise will be larger. If 1,000 J of heat is absorbed by a 2 kg block of lead then the temperature of the block doesn't rise as much since the energy is shared between more particles.
