Answer:
HEAT FLOWS INTO THE SURROUNDING FROM THE SYSTEM AND THE SIGN OF THE SYSTEM WILL BE POSITIVE.
Explanation:
This is so of an endothermic reaction and the contraction of the gas is an endothermic one because the total heat content of the products formed is more than that of the reactants and the gas therefore absorbs heat from the surrounding during the contraction. An endothermic reaction is one in which heat is absorbed from the surroundings and the change in heat content ΔH of is positive.
The reaction for the contraction of the gas produces + 10 J of heat.
Answer:
If the atoms get two close then the nuclii will repell each other.
Explanation:
Since electrons are negative they are attracted to the nucleus because it is positive. If two atoms get close enough together then the electrons of each atom will be attracted to both nuclii.

Torque is equal to force times distance. first calculate the weight of the 8-0 kg weight, using the formula:
F = mg
where g is the accelration due to gravity ( 9.81 m/s^2)
F = 8 kg ( 9.81 m / s^2 )
F = 78.48 N
and torque = Fl
where l is the distance
t = (78.48 N ) ( 0.55 m )
t = 43.16 Nm is the torque
