Answer:
ΔU = -6.2 × 10⁴ J
Explanation:
The system absorbs 965 J of heat, that is, q = 965 J.
The work (w) can be calculated using the following expression.
w = -P . ΔV
where,
P is the external pressure
ΔV is the change in the volume
w = - (1.90 × 10⁵ N/m²) × (0.51 m³ - 0.18 m³) = -6.3 × 10⁴ J
The change in the internal energy (ΔU) is:
ΔU = q + w = 965 J + (-6.3 × 10⁴ J) = -6.2 × 10⁴ J
Answer:
B. The elements that have similar densities and atomic sizes
Explanation:
Answer:
No, only the wiehgt, because the gravitational pull on the two, are diffrent. 3kg on the moon may be 6kg here on earth. but in the end, the rock still holds however much rock it held in the begining.
Explanation:
When a metal bonds with another non-metal an ionic bond is formed
It is an ensemble of similar cells
