Answer:
The volume of water that was in the kettle is 1170 
Explanation:
Given:
Power, P = 2.0 kW = 2000 W, Mass of stainless steel, 
= 710 g = 0.71 kg at temperature of 
Part A:
If it takes time, t = 3.5 minutes to reach boiling point of water 
, then from conservation of energy,
Total energy supplied by the burner = Total heat gained by the water and the stainless steel to rise from to
i.e. Pt = 
(100 - 20 ) + 
(100 - 20 )
= 
= 1.17 kg
where = 4200 J/Kgk (specific heat capacity of water), = 450 J/Kgk (specific heat capacity of steel)
But volume of water in the the kettle, v = 
∴ v = 1170
Theories have both an explanatory an a predictive function. True

The true statement about ligand gated sodium ion channels in neurons are open in response to chemical messenger and hyperpolarize the membrane.
<h3>What are ligand gated sodium ion channels?</h3>
Ligand gated sodium ion channels are the channels present in the neurons. Ion moves through this channel inside the cell or outside the cell.
Thus, the correct option is a) Open in response to chemical messenger and depolarize the membrane.
