Why nichrome wire is used as heating element? ​

Chemistry
1 answer:
Salsk061 [2.6K]3 years ago
5 0

Answer:

Nichrome wire is used as a heating element because it is very stable, even at high temperatures. Unlike other metals, it will not melt even when generating large amounts of heat. Ironically, nichrome actually has low electrical resistance, the property that causes the wire to heat.

PLEASE HELP ASAP
Kruka [31]

The mass stays constant as a substance changes from a liquid to a gas.  

The Law of Conservation of Mass states that, in ordinary chemical reactions, mass is neither destroyed nor created.


That is, the mass of the reactants must equal the mass of the products.


2H₂O(ℓ) ⟶ 2H₂O(g)


   1 g              1 g


If the mass of liquid water is 1 g, the mass of the water vapour must be 1 g.


Even though the water vapour is a gas and you can’t see it, it still has a mass

of 1 g.

Loy and Sam have a dog that has a spotted coat. The dog is also excellent at performing tricks.
Wewaii [24]

Answer: the correct option is A ( The spotted coat is an INHERITED TRAIT, and the ability to perform tricks is a LEARNED TRAIT.

Explanation:

Dog is one of the first domesticated animal by man because it has the ability to perceive information and retain it as knowledge for applying to solve problems.

Therefore, the ability to perform tricks is a LEARNED TRAIT. This is so because they have acquired the ability to understand and communicate with humans, and they are uniquely attuned to human behaviors.

INHERITED TRAIT is a trait that can be passed down from one generation to another which are found in genes within the strands of dogs DNA. Some of the inheritable traits includes the following:

- coat color,

- ear type, and.

- tail style.

Therefore the spotted coat is an INHERITED TRAIT
