The answer is B because solids have a definite shape and volume

Answer: D. solids and liquids only

Explanation:

Solids have definite volume because they have almost no inter-molecular space between its molecule, they are closely packed and rigid in their structure and hence they also have a definite shape.

In case of liquids we have a little inter-molecular space which makes the liquid-bulk flexible enough to attain any shape but this inter molecular space is not sufficient enough to make them compressible making them negligibly compressible. Therefore liquids are also  considered to have a difinite volume.

But in the case of gases there is very large inter molecular space and the molecules make a random motion due to very weak force of attraction between them and the space between the molecules is compressible on the application of force. So, they don't have a definite shape and definite volume.

<h2>Answer:</h2>

<h3>Interconversion of matter refers to change of one State to another. it is a process by which matter changes from one State to another and back to original state, without any change in it's chemical composition. Solid can be converted into liquids by heating</h3>

A 248-g piece of copper is dropped into 390 mL of water at 22.6 °C. The final temperature of the water was measured as 39.9 °C.
Sedaia [141]

Answer:

335°C

Explanation:

Heat gained or lost is:

q = m C ΔT

where m is the mass, C is the specific heat capacity, and ΔT is the change in temperature.

Heat gained by the water = heat lost by the copper

mw Cw ΔTw = mc Cc ΔTc

The water and copper reach the same final temperature, so:

mw Cw (T - Tw) = mc Cc (Tc - T)

Given:

mw = 390 g

Cw = 4.186 J/g/°C

Tw = 22.6°C

mc = 248 g

Cc = 0.386 J/g/°C

T = 39.9°C

Find: Tc

(390) (4.186) (39.9 - 22.6) = (248) (0.386) (Tc - 39.9)

Tc = 335

A wagon is rolling forward on level ground. Friction is negligible. The person sitting in the wagon is holding a rock. The total
Rudik [331]

Answer:

a) 0.41 m/s

b) 0.51 m/s

Explanation:

(a)

M = total mass of wagon, rider and the rock = 93.1 kg

V = initial velocity of wagon = 0.456 m/s

m = mass of the rock = 0.292 kg

v = velocity of rock after throw = 15.4 m/s

V' = velocity of wagon after rock is thrown

Using conservation of momentum

M V = m v + (M - m) V'

(93.1) (0.456) = (0.292) (15.4) + (93.1 - 0.292) V'

V' = 0.41 m/s

b)

M = total mass of wagon, rider and the rock = 93.1 kg

V = initial velocity of wagon = 0.456 m/s

m = mass of the rock = 0.292 kg

v = velocity of rock after throw = - 15.4 m/s

V' = velocity of wagon after rock is thrown

Using conservation of momentum

M V = m v + (M - m) V'

(93.1) (0.456) = (0.292) (- 15.4) + (93.1 - 0.292) V'

V' = 0.51 m/s
