How do you say "I want a car?"자동차를 싶어요?

"What is this called?" How do you say "What is this called?" In korean. Like if you are at a street food vendor and you want to ask what one of the dishes are called, what do you say?

When they end a verb with 죠, what does that mean? Can you use it with all verbs?

How do you say "I'm cold" and "I'm hot" in Korean?

진짜 피곤해요 오늘가 제미없었어. 산책가었어고 한국어를 곤부했어요. 우리 선생님 진짜 많이 숙제 줬어요! 지금 판다양과 고슴도치 봐요. 제가 친구들이 그 드라마 촣아했니까 저도 봘거에요. 여즈음 잠들다 가 수 없어서 진짜 피곤해요... 잠 잘요! Today was a really boring day. I went for a walk and did my korean homework. Our teacher are really giving us a lot of homework! Now I'm watchin panda and the headgehog. My friends liked that drama so I will watch it as well. Lately I havent been able to fall asleep and because of that I'm really tired... Sleep well!
