Explanation:
On yeeeeeeeeeeeee
Answer:
Physical properties of matter are properties that can be measured or observed without matter changing to an entirely different substance.
Additional examples of physical properties include:
odor
boiling point
ability to conduct heat
ability to conduct electricity
ability to dissolve in other substances
Because they have a full outer shell and they are both noble gases...Because the outer shell has attained stable electronics configuration of octate rule this it is with noble gas as helium.
Hope I helped!
Answer:
atoms have a positive nucleus and negative electrons,an atoms electron configuration the outermost electrons determines how the atom can interact with the other atoms and atom forms another atom for sharing electrons.
Answer:
Q = 440 J
Explanation:
Given data:
Heat required = ?
Initial temperature = 25°C
Final temperature = 40°C
Mass in gram = 20 g
Specific heat capacity = 1.1 J/g.°C
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 40°C - 20°C
ΔT = 20°C
Q = 20 g×1.1 J/g.°C × 20°C
Q = 440 J
