Answer:
b. keeping milk cold
Explanation:
The cool temperature in the fridge will stop it from going to any further reactions so it won't get spoilt
Answer:
V = 0.5 L
Explanation:
Given data:
Moles of nitrogen = 2.23×10⁻² mol (0.0223 mol)
Temperature = 273 K
Pressure = 1 atm
Volume = ?
Solution:
PV = nRT
V = nRT / P
V = 0.0223 mol × 0.0821 atm. mol⁻¹. L . k⁻¹ × 273 K / 1 atm
V = 0.5 L
It wont melt like gold and copper would at that temperature
