Intrusive igneous rocks cool down from magma slowly because they form underneath the surface, that will make them have large crystals.
Extrusive igneous rocks cool down from lava rapidly because they form at the surface, so that will make them have small crystals.
An electric power measure the rate of electrical energy transfer by an electric circuit per unit of time.
Specific heat formula is Q=M*C*ΔT
Q is amount of energy (4786 J)
M is mass (89.0 g)
C is specific heat (unknown, answer will be in J/gºC)
ΔT is the change in temp (89.5-23.0=66.5ºC)
Let's plug it in.
4786=89.0(C)(66.5)
4786=5918.5(C)
/5918.5
C=.8086508406 J/gºC
with sig figs...
C=.809 J/gºC
Answer:
The value of pressure inside the cylinder is 18.68 K Pa.
Explanation:
Given data
Height h = 0.14 m
Density 
= 13600 
We know that
Pressure inside the cylinder is given by the formula
P = g h ------- (1)
here
= density of fluid = 13600
g = acceleration due to gravity = 9.81 
h = height of the cylinder = 0.14 m
Put all the values in above equation
P = 13600 × 9.81 × 0.14
P = 18678.24 Pa
P = 18.68 K Pa
Therefore the value of pressure inside the cylinder is 18.68 K Pa
