<h3>Answer:</h3><h2>Chemical properties</h2><h3>Explanation:</h3>
By its very definition, a chemical property is one which is exhibited as a result of a chemical reaction. This may happen during or after the reaction. This is because in a chemical reaction there is a transformation in the physical composition of the components and this directly affects its chemical properties.
Answer: The specific heat of the liquid is 
Explanation:
As we know that,
.................(1)
where,
q = heat absorbed or released
= mass of glass = x kg
= mass of liquid = x kg
= final temperature =
= temperature of glass = 
= temperature of liquid = 
= specific heat of glass = 
= specific heat of liquid= ?
Now put all the given values in equation (1), we get
![-[(x\times 840\times (53-83)]=x\times c_2\times (53-43)](https://tex.z-dn.net/?f=-%5B%28x%5Ctimes%20840%5Ctimes%20%2853-83%29%5D%3Dx%5Ctimes%20c_2%5Ctimes%20%2853-43%29)
Therefore, the specific heat of the liquid is
An ocean ridge is an underwater mountain system which is the result of tectonic plate movement. Its formation involves two processes: ridge-push and slab pull. The former occurs when the growing bulk of the ridge pushes the rest of the tectonic plate away from the ridge. Oftentimes, they go towards a subduction zone. In this zone, the latter, which is the slab pull comes into effect. This is the weight of the tectonic plate subducted or pulled down below the overying plate tagging along the rest of the plate behind it.
They are generally located halfway between two continents.
The best answer is:
a. Extrusive igneous rocks
In general, rocks that are formed by the cooling of magma are classified as igneous rocks. The key word however in this case is "lava," which is magma that reached the surface. This is what makes it an extrusive igneous rock, because it formed in the surface.
