Explanation:
It is given that,
Resistance, R = 20 ohms
Voltage of the battery, V = 10 V
We can find current flowing through the circuit using Ohm's law as follows :
V = IR
It can be seen from the Ohm's law, that the current is directly proportional to the voltage. It means that if the battery is replaced by a battery that provides a larger voltage, the current through the circuit will be more than 0.5 A i.e. it increases.
Answer:
300K, 600K
Explanation:
ΔS =nCp ㏑()
= (2.5) (78.314) ㏑() = 14.41
Qp =(2.5) (8.314) (T2-T1)
= 6236 J.
=> 20.8 (T2-T1) - 6236
=> T2-T1 = 300
=> T2=T1 + 300
20.8 ㏑() =
=>
=> T1 = 300K
=> T2 = 600K
Answer:
It is sensible heat- the amount of heat absorbed by 1 kg of water when heated at a constant pressure from freezing point 0 degree Celsius to the temperature of formation of steam i.e. saturation temperature
So it is given as - mass× specific heat × rise in temperature
i.e. 4.2 × T
4.2 × (100–0)
So it is 420kj
If you ask how much quantity of heat is required to convert 1 kg of ice into vapour then you have to add latent heat of fusion that is 336 kj/kg and latent heat of vaporization 2257 kj/kg (these two process occur at constant temperature so need to add rise in tempeature)
So it will be
Q= 1×336 + 1× 4.18 ×100 + 1× 2257
Q = 3011 kj
Or 3.1 Mj
Hope you got this!!!!!!
Answer:
Atoms with a low electronegativity, like lithium, have a weak attractive force for electrons because they have few valence electrons and aren't close to having eight valence electrons.
Explanation:
Just did this question, guessed, and somehow got it right. Hope this helps!!!
The Calvin cycle<span> refers to the light-independent reactions in photosynthesis that take place in three key steps. Although the </span>Calvin Cycle<span> is not directly dependent on light, it is indirectly dependent on light since the necessary energy carriers (ATP and NADPH) are products of light-dependent reactions.
So basically it indirectly needs the light, even it's called light-independant reaction.
So the answer is the last one.</span>
