Hey there!
When plants grow towards the sunlight they get more light.
This is because the sun gives light. It wouldn't be "C" because sunlight makes plants survive, it wouldn't be "A" because sunlight doesn't decrease the size, and it wouldn't be "D" because the sunlight only makes it survive, not actually live longer. This means your answer is option B: they get more light.
Hope this helps
Have a great day (:
Solution :
Given :
Initial temperature of the refrigerant is :
= ( 39.37 + 273 ) K
= 312.3 K
Room which is maintained at constant temperature is :
= (22+273) K
= 295 K
The thermal energy transferred to the room is :
Q = 400 kJ
=
Therefore, the total entropy generation during the thermal energy process is :
Here, -Q = heat is leaving the system maintained at a temperature of K.
+Q = heat is entering the system maintained at a temperature of K.
Therefore, substituting the values :
= [-1280.8197 + 1355.9322]
= 75.1125 J/K
= 0.0751125 kJ/K
= 0.075 kJ/K
B) chemical bond i believe is the correct answer
Answer:
0.52 mol
Explanation:
Using the general gas equation formula:
PV = nRT
Where;
P = pressure (atm)
V = volume (Liters)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
At STP (standard temperature and pressure), temperature of a gas is 273K, while its pressure is 1 atm
Using PV = nRT
n = PV/RT
n = (1 × 11.74) ÷ (0.0821 × 273)
n = 11.74 ÷ 22.41
n = 0.52 mol
There are 0.52 moles in the basketball
