Energy to thermal energy.

Chemistry
1 answer:
sergiy2304 [10]3 years ago
3 0

A hair dryer converts "electrical energy" to "thermal energy".

Option: C

<u>Explanation</u>:

The "electricity" is converted to "heat energy" in a "wire coil". Here electricity process "air" out of "the hair dryer" with the help of forced convection. Most hairdryers use a nichrome wire coil that will not oxidize when heated and allowing it to "blow" the hair dry with high temperature air which speeds up evaporation. Thus "wire heats" the "air faster", in most of the "hair dryers" the "air" is only in "the barrel" for "half of a second".

what is an empirical formulaWhat is the percent composition by mass of nitrogen in (NH4)2CO3 (gram-formula mass = 96.0 g/mol)?
Margarita [4]

Answer:

Percentage composition = 14.583%

Explanation:

In chemistry, the emprical formular of a compound is the simplest formular a compound can have. It shows the simplest ratio in which the elements are combined in the compound.

Percentage composition by mass of Nitrogen

Nitrogen = 14g/mol

In one mole of the compound;

Mass of Nitrogen = 1 mol * 14g/mol = 14g

Mass of compound = 1 mol * 96.0 g/mol = 96

Percentage composition of Nitrogen = (Mass of Nitrogen /  Mass of compound) * 100

percentage composition = 14/96   * 100

Percentage composition = 0.14583 * 100

Percentage composition = 14.583%

A 220.0-mL sample of helium gas is in a cylinder with a movable piston at 105 kPa and 275K. the piston is pushed until the sampl
nignag [31]
Using the general gas equation:

P₁V₁/T₁ = P₂V₂/T₂

(105*220)/275 =   (P₂*95)/310

(105*220)*310/275  = P₂*95

 (105*220*310)/(275*95)  =  P₂

       274.11        =  P₂

       P₂  = 274.11 kPa

       New Pressure =  274.11 kPa
