Answer:

right answer is A bcz

Explanation:

In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond.

How much heat is required to warm 50.0 g of ice from -10.0oC to 0.00oC, melt the ice, warm the water from 0.00oC to 100.0oC, boi

ludmilkaskok [199]

The total heat required to convert the ice to steam is 155,000 J.

The given parameters:

Mass of the ice, m = 50 g
Initial temperature of the ice, t = -10 ⁰C
Final temperature of the ice, T = 0⁰C, 100⁰C and 120⁰C
Specific heat capacity of water = 4.184 J/g⁰C
Heat of fusion of ice, = 333.55 J/g
Heat of vaporization, = 2,230 J/g

The heat required to raise the temperature to 0⁰C is calculated as;

$Q = mc\Delta t\\\\Q_1 = 50 \times 4.184 \times (0 - (-10))\\\\Q_1 = 2092 \ J$

The heat required to melt the ice is calculated as follows;

$Q_2 = mL_f\\\\Q_2 = 50 \times 333.55 \\\\Q_2 = 16,677.5 \ J$

The heat raise the temperature to 100⁰C is calculated as;

$Q_3 = 50 \times 4.184 \times (100 - 0)\\\\Q_3 = 20,920 \ J$

The heat required to boil the water is calculated as follows;

$Q_4 = mL_v\\\\Q_4 = 50 \times 2230\\\\4_4 = 111,500 \ J$

The heat raise the temperature to 120⁰C is calculated as;

$Q_5 = 50 \times 4.184 \times (120 - 100)\\\\Q_5 = 4,184 \ J$

The total heat required is calculated as follows;

$Q_t = Q_1 + Q_2 + Q_3 + Q_4 + Q _5 \\\\Q_t = 2092 + 16,677.5 + 20,920 + 111,500 + 4,184\\\\Q_t = 155,373.5 \ J\\\\Q_t \approx 155,000 \ J$

A forklift applies a force of 2,000 N to raise a box 3 m.

anygoal [31]

If the force is applied to lift the box, then there is no work done as the displacement of the box is not in the same direction of the box.

However, if the force is being applied to move the box in the direction of the force, then the work done is:

Work = force x distance

Work = 1500 x 3

Work = 4,500 Joules
