A piston releases 18 J of heat into its surroundings while expanding from 0.0002 m2 to 0.0006 mº at a constant pressure of 1.0 x 105 Pa. What are the
correct values for heat and work for the piston?
A. Q = -18 J, W = +40 J
B. Q = +18 J, W = +40 J
C. Q = -18 J, W = -40 J
D. Q = +18 J, W = -40 J

you go to your settings preference and in the end youll see sth that says "i want to delete my acc" click on it and u'll acc will be deleted but u have to wait.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
