Answer:

Because the cohesive forces inside the droplets are stronger than the adhesive forces between both the drops and the wax, water does not penetrate waxed surfaces. Because the adhesive forces between the liquid and the glass are stronger than the cohesive forces inside the water, water wets glass and spreads out across it.

Which element would mostly have chemical properties similar to that of magnesium (Mg)?
DanielleElmas [232]

The elements of same group are placed in same group as they have similar properties. So Calcium is the element which resembles Mangesium.

Calcium and Magnesium both are alkaline earth metals.

They have similar properties as they have similar outer or valence shell electronic configuration

The general electronic configuration of alkaline earht metal is ns2

The electronic configuration of Mg [atomic number 12] and Ca [atomic number 20] are

[Ne]3s^{2}  and [Ar]4s^{2} respectively.

When you transferred the hot metal from the boiling water and into the calorimeter (coffee cup), if the thermometer touched the
sergey [27]

When you transferred the hot metal from the boiling water and into the calorimeter,  The effect will be

  • Change in temp is positive
  • Temp of metal V, dT=-ve
  • No change occurs in the specific heat of metal

This is further explained below.

<h3>What is the Specific heat of the metal?</h3>

a )Since the metal of the cup is hot and the water inside is cold, the water's temperature will rise as heat is transferred from the metal to the liquid.

Change in temp is positive

b)

Due to (a), heat is lost from the food to the water in the cup, lowering the metal's temperature.

Temp of metal V, dT=-ve

c)

No change occurs in the specific heat of metal because of its constant property.
