In short, heat flows from the warmer to the cooler body.
总之，热总是从高温物体流向低温物体。
Heat flow from a hotter to a cooler body is a process of energy transfer tending to equalize temperature.
热从高温物体流向低温物体是一个能量传递过程，它使温度趋于均匀。
In this case the hotter body is the refrigerant gas and the cooler body comprises the fins of the condenser.
这一情况中，较热物体是气态制冷剂，较冷物体包括冷凝器的那些散热片。
The chip could also use thermoelectric materials, which produce an electric current when exposed to two different temperatures-such as body heat and the (usually) cooler air around us.
芯片也可以使用温差热电材料- - -这种材料因环境中两种不同温度而产生电流- - -例如身体温度和(通常是)我们周围的更凉的空气。
The researchers think the cooler night and early-morning temperatures, which would help dissipate body heat and increase oxygen availability, may be more helpful than any tailwind assist.
研究者认为夜晚和凌晨的寒冷比较方便身体散发热量，增加氧气的可用性，可能比顺风更有利。
A spicy drink might seem counter-intuitive when temperatures heat up, but spicy foods actually help your body regulate its temperature. This ginger cooler will do the trick nicely!
大热天喝辣味饮料听起来挺反常的，但辣味食物的确有助人体调节体温——姜味饮料就有这样的良好功效。
If air in the atmosphere is cooler than brain and body temperatures, taking it in quickly cools facial blood that, in turn, cools the brain and may even alter blood flow.
如果环境空气的温度比大脑和身体的温度低，把它快速吸入可以冷却面部血液，当然，也为大脑甚至血液循环降了温。
This makes the central part of the body cooler and makes the hands and feet warmer.
这样身体的中心部分就会降低温度，使手和脚暖和起来。
Heat never flows spontaneously from a cooler to a hotter body.
热决不会自发地从低温物体流向高温物体。
Keep cool - you fall asleep faster and sleep better if the bedroom is cooler. A lower room temperature lowers core body temp, and helps you go to sleep.
温度低一点—如果卧室温度低一点，那你能更快入梦，睡眠质量也会更好。卧室里的温度低一点可以降低身体活动的温度，从而有助你入睡。
In the past some people thought that heat was a fluid, because it can flow from a hot body to a cooler one until both are at the same temperature.
在过去，一些人认为热是流体，因为它能。一个热的物体流到一个较冷的物体，一直到这两个物体温度相同为止。
Heat can be conducted from a hot body to a cooler one until both are at the same temperature.
热可以从一个热的物体传到一个较冷的物体，直到两者温度相同为止。
Blood in the tiny vessels near the skin can dissipate heat into the air, if the air is cooler than the body.
当气温低于人体温度时，皮肤下的微小血管里流动的血液可以把热量散发到空气中。
Blood in the tiny vessels near the skin can dissipate heat into the air, if the air is cooler than the body.
当气温低于人体温度时，皮肤下的微小血管里流动的血液可以把热量散发到空气中。
