THE THREE STATES OF MATTER
/ðə θriː steɪts əv ˈmætə/
There are three states of matter.
/ðeə ə θriː steɪts əv ˈmætə/
We know water in all three states.
/wi nəʊ ˈwɔːtə ɪn ɔːl θriː steɪts/
We have solid water which we call ice; liquid water; and a gas which we call steam.
/wi həv ˈsɒlɪd ˈwɔːtə wɪʧ wi kɔːl aɪs ˈlɪkwɪd ˈwɔːtə ənd ə gæs wɪʧ wi kɔːl stiːm/
When we place a solid in a vessel, it keeps its own size and shape.
/wen wi pleɪs ə ˈsɒlɪd ɪn ə ˈvesl ɪt kiːps ɪts əʊn saɪz ənd ʃeɪp/
A liquid does not keep its own shape.
/ə ˈlɪkwɪd dʌz nɒt kiːp ɪts əʊn ʃeɪp/
It takes the shape of the vessel, but keeps its own size.
/ɪt teɪks ðə ʃeɪp əv ðə ˈvesl bʌt kiːps ɪts əʊn saɪz/
A gas takes both the size and the shape of the vessel.
/ə gæs teɪks bəʊθ ðə saɪz ənd ðə ʃeɪp əv ðə ˈvesl/
A solid has a definite size and a definite shape.
/ə ˈsɒlɪd həz ə ˈdefɪnɪt saɪz ənd ə ˈdefɪnɪt ʃeɪp/
A liquid has a definite size, but no definite shape.
/ə ˈlɪkwɪd həz ə ˈdefɪnɪt saɪz bɜː nəʊ ˈdefɪnɪt ʃeɪp/
A gas has no definite size or shape.
/ə gæs həz nəʊ ˈdefɪnɪt saɪz ə ʃeɪp/
These three states depend on the freedom of the molecules to move about.
/ðiːz θriː steɪts dɪˈpend ɒn ðə ˈfriːdəm əv ðə ˈmɒlɪkjuːlz tə muːv əˈbaʊt/
In a solid the molecules move very slowly; in a liquid they move about more freely; in a gas they about with great speed.
/ɪn ə ˈsɒlɪd ðə ˈmɒlɪkjuːlz muːv ˈverɪ ˈsləʊli ɪn ə ˈlɪkwɪd ðeɪ muːv əˈbaʊt mɔː ˈfriːlɪ ɪn ə gæs ðeɪ əˈbaʊt wɪð greɪt spiːd/
Is this body a solid or not?
/ɪz ðɪs ˈbɒdɪ ə ˈsɒlɪd ə nɒt/
It is not always easy to answer this question.
/ɪt ɪz nɒt ˈɔːlwəz ˈiːzɪ tʊ ˈɑːnsə ðɪs ˈkwesʧən/
A piece of pitch seems to be solid but when we place it in a vessel it slowly takes the shape of the vessel.
/ə piːs əv pɪʧ siːmz tə biː ˈsɒlɪd bʌt wen wi pleɪs ɪt ɪn ə ˈvesl ɪt ˈsləʊli teɪks ðə ʃeɪp əv ðə ˈvesl/
This shows that it really is a very thick liquid.
/ðɪs ʃəʊz ðæt ɪt ˈrɪəlɪ ɪz ə ˈverɪ θɪk ˈlɪkwɪd/
A thin jelly seems more liquid than pitch, but it does not take the shape of its vessel.
/ə θɪn ˈʤelɪ siːmz mɔː ˈlɪkwɪd ðæn pɪʧ bʌt ɪt dʌz nɒt teɪk ðə ʃeɪp əv ɪts ˈvesl/
This means that it is a real solid.
/ðɪs miːnz ðæt ɪt ɪz ə rɪəl ˈsɒlɪd/
THE THREE STATES OF MATTER
There are three states of matter.
We know water in all three states.
We have solid water which we call ice; liquid water; and a gas which we call steam.
When we place a solid in a vessel, it keeps its own size and shape.
A liquid does not keep its own shape.
It takes the shape of the vessel, but keeps its own size.
A gas takes both the size and the shape of the vessel.
A solid has a definite size and a definite shape.
A liquid has a definite size, but no definite shape.
A gas has no definite size or shape.
These three states depend on the freedom of the molecules to move about.
In a solid the molecules move very slowly; in a liquid they move about more freely; in a gas they about with great speed.
Is this body a solid or not?
It is not always easy to answer this question.
A piece of pitch seems to be solid but when we place it in a vessel it slowly takes the shape of the vessel.
This shows that it really is a very thick liquid.
A thin jelly seems more liquid than pitch, but it does not take the shape of its vessel.
This means that it is a real solid.
