How many joules are required to heat 2 l of water in a pot from 20 ◦c to the boiling point of water? the specific heat of water
miss Akunina [59]
  The  joules  required  to   heat 2L  of  water  in  a  pot  from  20  c  to  the  boiling  point  of  water  is  calculated     using the following  formula

  Q=    MC  delta  T
M  = mass  =   density  x   volume(  2  x 1000= 2000ml)
M  =     1g/ml  x2000  ml  =  2000g
C  =  specific  heat   capacity =  4.18  g/c
delta  T  =  change  in  temperature  =  100 c (  boiling  point  of  water)   -  20 c =  80 c 
Q  is therefore  =   2000 g x 4.18 j/g c  x  80c  =  668800j

the water in a 150-mL flask is poured into a beaker that contains 600 mL of ethyl alcohol. Which sis stands solvent in this mixt
Alekssandra [29.7K]

Taking into account the definition of solvent and solute, ethyl alcohol because it has a much larger volume than water.

<h3>Definition of solute and solvent</h3>

The solution is a homogeneous mixture of two or more components that have the same chemical and physical properties in a single phase. A solution is made up of two main components: the solute and the solvent.

The solute is the substance that dissolves in a solution and is usually found in a lower proportion than the solvent.

Solvent is the substance in which a solute dissolves, resulting in a chemical solution and is the component that is found in the highest proportion in the solution. It will always be the solvent who will determine the state of the matter that will have the solution.

<h3>Solute and solvent in this case</h3>

In this case,  you consider that the solute is the component in less quantity and the solvent is the major component, and you know that the water in a 150 mL flask is poured into a beaker that contains 600 mL of ethyl alcohol.

Then, ethyl alcohol because it has a much larger volume than water.
