Answer:-
86.794 K
Explanation:-
Initial temperature T 1 = 32 C + 273 = 305 K
Initial Pressure P 1 = 49.9 KPa
New Pressure P 2 = 14.2 KPa
The Volume remains same since it is rigid.
∴V 1 = V 2 = 50.0 L
Using the relation
P 1 V 1 / T1 = P 2 V 2 / T 2
New temperature T 2 = P 2 V 2 T 1 / ( P 1 V 1)
= 14.2 KPa x 50.0 L x 305 K / ( 49.9 KPa x 50.0 L)
= 86.794 K
B. Quartzite is not granular, while sandstone is granular.
C. Quartz sandstone has undergone metamorphism, while quartzite has not.
D. A broken piece of quartzite will break through, not around, quartz sand grains.
D. A broken piece of quartzite will break through, not around, quartz sand grains.
Quartzite and quartz sandstone have the same chemical formula (SiO_2)
Quartzite is a metamorphic rock. Heat and pressure have compressed the sand into a strong network of interlocking quartz grains.
Quartzite is so tough that it breaks through the sand grains rather than around them as in sandstone.
Answer:
D. A broken piece of quartzite will break through, not around, quartz sand grains
