I've been having so much trouble in these types of questions, but now it's so much more clearer and simpler. Thank you again Cognito!

Sometimes we're expected to know the state symbols to reactions we haven't seen before, and they don't tell us their melting or boiling points. How are we supposed to know?

IKR

[@_Dreamer_9306]

Ask your teacher or check your notes, most probably, you might just have to go with a general estimate for the general melting and boiling points for solids, liquids and gases. But answers definitely won't be 100% correct that way.

[@hdjsjssj5378]

In the exam you should have a periodic table with you and each group of elements would have similar melting/boiling point and i guess you could estimate around that but I’m not sure :/

[@MONYESTER]

Bro... this guy is an absalout legend. He explains way better than my teachers.

[@AbhayHero11]

is there a way to like all the videos at once cause there are a lot of videos on here to like and they all deserve a like

[@spellmyname6884]

Here’s the thing my exam doesn’t tell us the melting point and boiling point

[@Cognitoedu]

That’s rough!! Look up the specification and find all the elements you need to know the melting and boiling points of! Slap them on flash cards and practise for a few mins every day - you’ll know them in no time! Good luck 🙌

[@StrawberryS-vk5my]

do you have any quizlet flashcards or a pack of set where you have written all the chemical equations we need to know for GCSE? And tysmmmm for these videos :)

@Rajeev Vij yeah

[@A2G2Anims040]

Yeah bro not everyone is able to understand hindi

[@smaxo9368]

Hi! Can we tell the physical state of a compound based on the type bonding they form?

[@lazy404]

Yes , but you could mess it up so it's not that dependable

[@naifahchy5508]

it would be better if all the vids were arranged in a playlist topicwise for better understanding but amazing vid anyway

[@guruofeverything6379]

Thank you

[@abecoyne6302]

Congrats on 1k 🥳🥳

Thanks Abe!!! Big day for us :D

No problem, i can't believe that at the start of this week you where at like 600 now in less than a week your at 1k i can't wait for you to be the new free science lessons 😂

Nope
