temperature. The element gallium is a byproduct of the production of aluminum and zinc. Most gallium is extracted from the crude aluminum hydroxide solution of the Bayer process. Gallium easily bonds with most metals and is often added to low melting alloys. Gallium has the second largest liquid range of any element and is one of the few materials that are near liquid form. Gallium also expands as it

UTAR FHSC1134 Inorganic Chemistry Trimester 3 Experiment 1 ________________________________________________________________________ Title: Investigating the Properties of Period 3 Oxides Aim: To examine the oxides of Period 3 elements and describe their structure and bonding. Introduction: Generally‚ there are oxides of metals and non-metals. Metals burn in oxygen to form basic oxides while non-metals form acidic oxides. Structurally‚ they are covalent or ionic compounds. You are to

During the experiment‚ aluminium and mild steel was used to demonstrate how the materials behave during the testing condition. By measuring the applied torque with respect to the angle of twist‚ the Torsional rigidity (GJ)‚ the Modulus of Rigidity (G) and the shear yield stress (τ) for ductile materials‚ mild steel and aluminium. INTRODUCTION The purpose of this experiment is to study and to compare the behaviour of ductile

Usually‚ four types of materials are commonly used for actuators: * shape memory alloys‚ * piezoelectric ceramics‚ * magnetostrictive materials‚ * and electrorheological/magnetorheological fluids. Shape memory alloys are metals that‚ after having been deformed‚ revert back to their original shapes when temperature is changed. Piezoelectric ceramics expand and contract in response to an
