1a Absolute Zero (is at zero degrees Kelvin viz. 0K)

1a Absolute Zero

Do you know the number of letters in these answers?

4d may be a cross-reference to Qu 14

Thank you so much to you both.

The clue for 14a - Slow down and move off the road - something's worn out...

4d - 14 has no arms in gun turret (2 words)

[gen2]

OK, so 14d = PULLOVER - that will make 4 a TANK TOP

It makes it a lot easier to answer if you tell us the number of letters.

Thank you so much.
