According to the second law of thermodynamics, ambient heat cannot move to an object and make it hotter than the surroundings. Actually, ambient heat CAN do so, in violation of the second law. The famous floating water bridge becomes hot by extracting heat from the colder surroundings:

"It emits heat...the bridge is hot." https://youtu.be/hPM1l93mGZw?t=525

Water in an electric field automatically becomes a perpetual-motion machine of the second kind. Vigorous motion is generated that can do work (e.g. by rotating waterwheels) at the expense of ambient heat (no other source of usable energy), in violation of the second law of thermodynamics:

As I have already said, water in an electric field automatically becomes a perpetual-motion machine of the second kind. An example was published and immediately forgotten in 2002:

"A deviation from the second law of thermodynamics has been demonstrated experimentally for the first time. [...] To test the idea, the researchers put about 100 latex beads - each 6.3 µm across - into a WATER-FILLED CELL, which was placed on the stage of a microscope. The researchers focused a laser onto one of the beads, which induced a dipole moment in the bead and drew it towards the most intense region of the ELECTRIC FIELD in the laser beam." http://physicsworld.com/cws/article/news/2002/jul/16/small-systems-defy-second-law

Nature: "Second law broken. Researchers have shown for the first time that, on the level of thousands of atoms and molecules, fleeting energy increases violate the second law of thermodynamics. [...] They found that over periods of time less than two seconds, variations in the random thermal motion of water molecules occasionally gave individual beads a kick. This increased the beads' kinetic energy by a small but significant amount, in apparent violation of the second law." http://www.nature.com/news/2002/020722/full/news020722-2.html

Scientific American: "Second Law of Thermodynamics Violated. [...] ...the water molecules interacted with the bead in such a way that energy was transferred from the liquid to the bead. These additional kicks used the random thermal motion of the water to do the work of moving the bead, in effect yielding something for nothing. For periods of movement lasting less than two seconds, the bead was almost as likely to gain energy from the water as it was to add energy to the reservoir, the investigators say." https://www.scientificamerican.com/article/second-law-of-thermodynam/
