Answer:
E
Explanation:
A miscelle has a an ionic head which is hydrophillic and interacts effectively with water, helping the miscelle to dissolve. The tail is hydrophobic, it dissolve the grease or stain and removes it from the fabric. The hydrophobic tail extends outside the water, while the hydrophillic head extends into the water. This enables the cleansing action of soap
The term which is used is homogeneous.
when sugar is completely dissolved in the water, the mixture or solution homogeneous, both in same phase and same uniform texture that is liquid.
There two types of mixtures are heterogeneous and homogeneous in different phases.
If sugar is not completely dissolved in water and you see the crystals of sugar in water, then the solution will be heterogeneous.
Answer:
Option D. 1092K
Explanation:
T1 = 273K
V1 = V
P1 = P
V2 = 2V( i.e double of original volume)
P2 = 2P (i.e double of original pressure)
T2 =?
P1V1/T1 = P2V2/T2
PV/273 = 2P x 2V / T2
Cross multiply to express in linear form
PV x T2 = 273 x 2P x 2V
Divide both side by PV
T2 = (273 x 2P x 2V) / PV
T2 = 273 x 2 x 2
T2 = 1092K
