1) the mass of an object gives gravity, the more massive an object is the more gravity it has on the things around it
2)the earth's mass is so much greater than our own that we feel it's gravity stronger than say the moon which has a smaller mass than the earth
3) mass and how far away you are from the object
4)as mass increases so does gravity (sorry I do not remeber the equation but there are some specific ones for different situations between two massive objects)
5) when distance increases, gravity decreases (again I do not remeber by how much)
It is A; <span>[He] 2s</span>²<span> 2p</span>² is another way to put it
Nitrogen, arsenic, antimony & bismuth
Explanation:
Phosphorus belongs to the 15th group, that is nitrogen family.
Natures are decided by the number of valence electrons.
In a family, all elements have same outer electronic configuration or you say number of electrons.
General electronic con.: ns²np³
Answer:
Q = 10.10059 KJ
Explanation:
Given data:
Amount of water = 13.0 g
Initial temperature = 52.5°C
Final temperature = 238.2°C
Heat required to convert it into steam = ?
Solution:
Specific heat capacity of water is 4.184 J/g.°C
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 = 238.2°C - 52.5°C
ΔT = 185.7 °C
by putting values,
Q = 13.0 g × 4.184 J/g.°C × 185.7 °C
Q = 10100.59 J
Jolue to Kj:
10100.59j × 1 KJ/1000 J
Q = 10.10059 KJ
