Answer:
The volcanoes are directly associated with the convergent type of plate boundary.
In a convergent boundary, two plates move towards each other. Due to their collision, a subduction zone is formed where the denser plate goes down below the other less dense plate, and the trench lies above this zone, which is a long, narrow depression and marks the boundary between the two distinct plates.
As the denser plate subducts, it melts and mixes up with the magma. This magma then rises upward due to the force exerted by the convection current. This magma then reaches the surface towards the over-riding plate, resulting in the formation of volcanoes, or volcanic or island arcs.
Thus, the convergence of two plates leads to the formation of a volcano.
by 68.0°C. What is the mass of the coin?
Please helppp!!!
The mass of the copper coin placed in 101g of water is 135.3g.
The mass of the copper coin can be calculated using the following expression:
Since; Q = mc∆T
Where;
According to the question;
COPPER METAL:
WATER:
m = 101g
c = 4.18 J/g°C
∆T = 8.39°C
⇒ 101 × 4.18 × 8.39 = (0.385 × m × 68)
⇒ 3542.09 = 26.18m
⇒ m = 3542.09 ÷ 26.18
⇒ m = 135.3g
Therefore, the mass of the copper coin placed in 101g of water is 135.3g.

Answer:
You should generally have one independent variable in an experiment. This is because it is the variable you are changing in order to observe the effects it has on the other variables.
