Answer:
54 is the correct answer to this question
Answer:
the heat gained by the system (gas) is 60 J.
Explanation:
Given;
work done by the gas sample, W = 150 J
change in internal energy, ΔU = -90 J
Apply the first law of thermodynamic;
ΔU = Q - W
where;
Q is the heat gained by the system
From the equation above;
Q = ΔU + W
Q = -90 + 150
Q = 60 J
Therefore, the heat gained by the system (gas) is 60 J.
Answer: 4.64 × 10^7 mg
Explanation:
Given:
T =1299g + 45.1kg
Convert kg to g
T = 1299g + 45.1kg ×1000g/kg
T = 1299g + 45100g
T = 46399g
T= 4.64 × 10^4 g
Convert to milligram
T = 4.64 × 10^4 g × 1000mg/g
T = 4.64 × 10^7 mg
Therefore, 1299g + 45.1kg = 4.64 × 10^7 mg
Answer: A
Explanation: Warm fronts cause snow flurries in the winter, while cold fronts cause several days of rainy weather so (C) wouldn’t be it. (D) is to Vague so it doesn’t best describe what occurs in a warm front. Last, (B) is wrong since the weather DOES change in a warm front. That leaves us with (A), so (A) is the correct Answer.
