Acylinder and piston assembly (defined as the system) is warmed by an external flame. the contents of the cylinder expand, doing work on the surroundings by pushing the piston outward against the external pressure. if the system absorbs 533 j of heat and does 488 j of work during the expansion, what is the value of δe? express the energy change as an integer and include the appropriate units.

The energy change for the given system: ΔE  = 45 J

Explanation:

According to the First Law of thermodynamics, the energy can't be created or destroyed and can only be converted into other forms.

ΔE = Q - W                                 equation 1

Given: ΔE is the change in the internal energy

Q is the heat absorbed by the system

W is the work done by the system

Given: Q = = 533 J, W = 488 J, ΔE = ?

Using equation 1, to calculate the change is the internal energy (ΔE),

ΔE = Q - W = 533 J - 488 J = 45 J

Therefore, the energy change for the given system: ΔE  = 45 J

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance

explanation:

i think option no d is the correct answer
