Learn the גמרא דף מב. “סבר רב יוסף למימר until אמר רב הונא בריה דרב יהושע (eight lines from the bottom of the Amud)

Review תוס’ “אבל

Tosfos explains the אמבטיה in the Halacha of our Gemara is a Kli Sheini. 

Why is it forbidden to pour cold water into the bath if it’s a Kli Sheini?

According to Tosfos – Why does everyone agree it is forbidden to pour cold water into a bath – Kli Sheini – of hot water as a gezaira to prevent one from pouring into a Kli Rishon, yet to pour cold water into a cup which is a Kli Sheini is a dispute between Beis Shammai and Bais Hillel if we make a Gezaira?

Bring a proof from Rashi whether the bath is a Kli Rishon or a Kli Sheini

In what way is the Ran’s explanation of the Gemara different than the explanation of Tosfos – תוס’ “נותן? 

Is it permitted to pour an abundance of cold water into a bath that is a Kli Rishon? 

How do we conclude according to halacha?
