Answer:
direct effect
Increasing the pressure increases the boiling point and decreasing the pressure decreases the boiling point
Answer:
Electron cloud
Explanation:
The electron cloud is an informal term in chemistry and physics. This region describes the negatively charged electrons in their orbit surrounding the nucleus in an atom. The nucleus has protons in it that have a positive charge on it. It is not easy to know where exactly an electron in any specific time but the electron cloud helps to know electron is moving in this specific area.
The least net force applied : Car 3(12 N)
<h3>Further explanation </h3>
Newton's 2nd law explains that the acceleration produced by the resultant force on an object is proportional and in line with the resultant force and inversely proportional to the mass of the object
∑F = m. a
Car 1 ⇒m=0.5 kg, a=36 m/s²
Car 2⇒m=0.8 kg, a=50 m/s²
Car 3⇒m=0.6, a=20 m/s²
Car 4⇒m=1, a=19~m/s²
Carbon dioxide sublimation
water evaporate
physical change is just change between solid/liquid/gas, other two are chemical changes
