ごはん is rice. If it has a time of day modifier like asa (morning) hiru (day) or ban (evening) then it is a meal. Morning rice is breakfast basically.

Most of the people say for example あさごはん instead of just ごはん and specify which meal they are talking about.

The same way you tell the difference between meal (as in corn meal, or any grain ground down to powder) and meal (a specific instance of eating).

Kind of like tea for us, afternoon tea, morning tea...

I also answered the same thing, but please correct me if I'm wrong, I think it's supposed to considered correct. Since Japanese's usually omit the "watashi" or "watashi-tachi" because it's going to be based on who are you speaking with?

I said this rice is cold

わたしたちつめたいごはんをたべます

Yeah there was no あの so over there made no sense lol. With adjectives though, there are "い" adjectives and "な" adjectives. All い adjectives end in い and can go before a noun without a particle. な adjectives end in whatever (some end in い to confuse you) and have the particle な between it and what it's modifying.

I did the same... I think its because cold is directly before rice making it an adjective. The subject being cold rice instead of describing the rice as cold...

The short grained, sticky Japanese rice tastes better cold. Think sushi. Also, as an ethnic Asian, if you miss the meal and want to eat, the rice comes out of the fridge. You don't want to keep rice outside. https://www.mirror.co.uk/lifestyle/family/reheating-rice-can-make-you-10119500

The first is cold wheather the other is cold to the touch.

I think that would end in the verb "desu" instead of "arimasu".

With the exception of the "A is a B" (A は B です) construction, the noun always needs to be followed by a particle. In this case, with the verb あります, the expected one is the subject particle が.

That has a completely different meaning. In English, this would mean that in some other place, the only rice they have is cold rice. In Japanese, the equivalent might be "そこのごはんはつめたいです"

Cold to the touch. The Japanese have at least two words for cold- tsumetai, cold to the touch and samui- cold weather. The Japanese have two words for hot- atsui. The two atsui words have different Kanji, but the same sound.

Yep.

Because in Japanese that would be このごはんはつめたいです. It's a different sentence.

It's because つめたい in this sentence is directly modifying the noun. つめたいごはん means "cold rice". "The rice is cold" would be ごはんはつめたいです.

You can't add words to the sentence structure. Some is a quantity and the sentence is not specifying an amount.

Arimasu means "exist." When we practice Japanese at home, we use it, for example, to say things like "dinner is ready (dinner exists)," or if one is looking for a snack, "there is cold pizza in the fridge (cold pizza in the fridge exists)." Desu is just a word to use when you are being polite. So, in the example here, picture your teenage daughter coming home saying she is hungry. You aren't going to prepare something for her, and expect her to do it herself. So you tell her- there's cold rice in the pot, and chicken in the fridge. Go and help yourself.

In contrast, in the examples you are giving, someone is eating. They put the rice in their mouth. They grimace and say, "Dangit woman, the rice is cold!"

That's a bug from the fact that "I have" can also be used in sentences like "I've got cold rice" for example. If it happens again, try reporting.

I think the British might still use "I've" like that. We've lost that usage in America a century ago.

Chopsticks. You might try it with seasoned cod roe.
