Answer:
3584.21 J/kg.K
Explanation:
Applying
Q = cm(t₂-t₁)........... equation 1
Where Q = Quantity of heat absorb, c = specific heat capacity of the metal, m = mass of the metal, t₁ = intial temperature, t₂ = Final temperature.
make c the subject of the equation
c = Q/(m(t₂-t₁)........... Equation 2
From the question,
Given: Q = 1362 J, m = 15.2 g = 0.0152 kg, t₁ = 17°C, t₂ = 42°C
Substitute these values into equation 2
c = 1362/0.0152(42-17)
c = 1362/0.38
c = 3584.21 J/kg.K
Answer:
Gases, liquids and solids are all made up of atoms, molecules, and or ions, but the behaviors of these particles differ in the three phases, gases are well separated with no regular arrangement. liquids are close together with no regular arrangement, and solids are tightly packed, usually in a regular pattern.
The substance most likely is an inert element because it is only composed of one kind of atom and cant be separated further. Also, it cannot be converted to another type of substance. An inert material doesn't react to any substance. Examples are Neon and Krypton.
Calcium is used to isolate Rb from molten RbX because calcium has a smaller atomic radius than rubidium.
A chemical element's atomic radius, which is typically the average or typical distance between the nucleus's core and the outermost isolated electron, serves as a gauge for the size of an atom. There are numerous non-equivalent definitions of atomic radius since the border is not a clearly defined physical entity. Van der Waals radius, ionic radius, metallic radius, and covalent radius are the four most frequently used definitions of atomic radius. Atomic radii are typically measured in a chemically bound condition since it is challenging to isolated individual atoms in order to measure their radii individually.
