Answer:

sublimation, melting, melting, sublimation

Step-by-step explanation:

Melting is defined by a process when any matter being in its solid state changes its state to liquid when introduced to heat while sublimation is a process when the matter in solid state changes directly to gaseous state when introduced to heat.

therefore,

"Iodide produces fumes when heating" is sublimation.

"An iceberg turn to ocean water" is melting.

"Candle wax turns to liquid when hot" is melting.

"Fog is created from dry ice" is sublimation.

Workers in an office of 60 staff were asked their favourite type of take-away.
nikdorinn [45]

Answer:

a = 84°

b = 36°

c = 24°

d = 84°

e = 132°

Step-by-step explanation:

The parameters of the workers in the office are;

The number of staffs in the office = 60 staffs

The take-aways are pizza, curry, fish & chips, kebab and other

The frequency for the above take-aways = 14, 6, 4, 14, and 22 respectively

The variables for the angles representing the above take-aways on the pie chart = 'a', 'b', 'c', 'd', and 'e'; respectively

In order to find the size of the angles that represent each group of workers in the pie chart, we find the ratio of the group size to the total number of workers and we multiply the result by 360° as follows;

∠a = 360° × 14/60 = 84°

∠b = 360° × 6/60 = 36°

∠c = 360° × 4/60 = 24°

∠d = 360° × 14/60 = 84°

∠e = 360° × 22/60 = 132°
