1. APPARATUS and EXPERIMENTAL TECHNIQUES 1.1. Vibration Isolation and Checks For the quantum phase slips to be useful as a probe of vortex nucleation mech- anisms, one must be able to observe slips which are due to intrinsic mechanisms. Previous work 12,13, 6,14,15 showed that above T = 150 mK thermally activated pro- cesses dominated slip production. A deviation from this dependence was seen at lower temperatures when large amounts of 3He impurities were present in the 4He sample ...

AQA GCSE Chemistry Paper 1 What is an *atom*? - ANS smallest part of an element What is an *element*? - ANS a substance that contains only one type of atom What are *chemical symbols*? - ANS - the letter or pair of letters that represents an element. - first letter is always capitalized What are *compounds*? - ANS substances in which atoms of two or more elements, which are chemically combined What is a *chemical formula*? - ANS a combination of symbols that shows t...

AQA GCSE Chemistry What is a mixture? - ANS Two or more elements not chemically bonded What is the difference between a compound and a mixture? - ANS Compounds have a fixed composition whereas mixtures do not. Mixtures are not chemically bonded but compounds are. Describe the process of filtration - ANS Pour the mixture onto the filter paper, the liquid simply passes through the filter paper into the flask. The insoluble solid cannot pass through and so it stays on the paper...
