1.	At 100°C, 150gm of cold water was mixed with 40gm of water. What was the temperature of cold water if the mixture was heated to 50°C ?
Answer» ONG>Answer: the answer is 30 Explanation: FINAL temperature of the MIXTURE = = [ m1 * T1 + m2 * T2 ] / (m1 + m2) = [ 50 gms * 20⁰ C + 50 gms * 40⁰C ] / (50+50) = 3,000 / 100 = 30⁰C

Answer» ONG>Answer:

the answer is 30

Explanation:

FINAL temperature of the MIXTURE =

= [ m1 * T1 + m2 * T2 ] / (m1 + m2)

= [ 50 gms * 20⁰ C + 50 gms * 40⁰C ] / (50+50)

= 3,000 / 100 = 30⁰C
