Answer:
obtuse
Step-by-step explanation:
as one angle is bigger than 90°
Assuming constant pressure, V/T = constant.
Where T is absolute temperature, and V is volume.
T1 = 60 ° + 273.15 = 333.15 K
V1 = 300 cm^3
T2 = 30°C + 273.15 = 303.15 K
V2 = ?
V1 / T1 = V2 / T2 = > V2 = [V1/T1] * T2
V2 = [300cm^3 / 333.15K] * 303.15K = 272.9 cm^3
Answer: 272.99 cm^3
