The energy needed to raise the temperature of water from 22.0ºC to 90.0ºC is c. 28.4 kJ.
<h3>What is specific heat?</h3>
The amount of energy needed to raise the temperature of one gram of a substance by one degree Celsius.
By the formula 
Q is the heat
m is the mass
c is the specific heat
Now, c = 4.184 J/g.K
The change in temperature is 22.0 ºC to 90.0 ºC
Putting the value in the equation
Thus, the energy needed to raise the temperature of water from 22.0ºC to 90.0ºC is 28.4 kJ

Answer:
X ray
Explanation:
i m not sure about this answer hope it helps :)
A.how many moles of aspirin are in one tablet
0.325 g ( 1 mol / 180.2 g ) = 1.80 x 10^-3 mol
B. How many moles of oxygen are in one tablet of aspirin
1.80 x 10^-3 mol C9H8O4 ( 4 mol O / 1 mol <span>C9H8O4) = 7.21 x 10^-3 mol O
</span>
C. How many atoms of carbon are in one tablet of aspirin
1.80 x 10^-3 mol C9H8O4 ( 9 mol C / 1 mol C9H8O4 ) ( 6.022 x 10^23 atoms C / 1 mol C ) = 9.76 x 10^21 atoms C
D. How many grams of oxygen in one tablet of aspirin
7.21 x 10^-3 mol O ( 16 g / mol ) = 0.12 g O
Light<span> transfers energy, and if this energy is absorbed it </span>will<span> heat the </span>food<span>. So yes visible lights do.</span>
