Gallium highly reactive (rubidium and caesium) nor highly toxic (mercury) and can therefore be used in metal-in-glass high-temperature thermometers. It is also notable for having one of the largest liquid ranges for a metal, and for having (unlike mercury) a low vapor pressure at high temperatures. Gallium's boiling point, 2673 K, is more than eight times higher than its melting point on the absolute scale, the greatest ratio between melting point and boiling point of any element. Unlike mercury, liquid gallium metal wets glass and skin, along with most other materials (with the exceptions of quartz, graphite, and Teflon), making it
Power posing al. In a 2016 study by Garrison et al. the effect of posture manipulation was combined with dominant vs. submissive gaze. Despite a large sample size, no effect was found on risk taking and, in contrast to original expectations, adopting an expansive pose reduced feelings of power. Deuter et al. (2016) investigated the effect of cognitive role taking and Cuddy's power posing manipulation in the Trier Social Stress Test; although role taking had an influence on the cortisol and testosterone response after stress, the posture manipulation had no effect on hormonal, behavioral or subjective measures. Where influences on hormones were
